Parental Bonus

""The whole secret to the success of a cartoon like Animaniacs is to appeal both to the kiddies who like animated slapstick, and to the college kids who like the quick inside jokes clearly intended to sail over the toddlers' heads. Then, sometimes, they'll throw in a reference to fingering a man's anus.""

- Cracked, The 6 Creepiest Things Ever Slipped Into Children's Cartoons

A joke on a children's TV show that children of the appropriate age would likely never get, but which their parents would. Serves as a way to keep the adults and older kids entertained and usually takes the form of an Homage to a movie or TV show that children would not normally be familiar with. This is the master trope to other "subliminal" tropes like a Double Entendre, Does This Remind You of Anything?, No Celebrities Were Harmed, or Getting Crap Past the Radar. It could also count as a Genius Bonus, since most children would have to be educated above their general age level to understand these.

Popularized by Sesame Street, with characters like Sherlock Hemlock and the Count, and thus most common on educational shows. Surprisingly, the barely intelligible Cookie Monster seems to get the most Parental Bonus lines, at least in recent history: "Me undergo sea-change," etc.

Of course, a badly done Parental Bonus will entertain neither the kids nor the adults, and may terrify the latter that the former actually will "get" it...

Golden Age animated shorts, especially those from Fleischer Studios and Warner Bros, often had material which would be considered Parental Bonus today (if people still got the references), as they were intended for all audiences (see Animation Age Ghetto). As a result, many cartoons had numerous double entendres and pseudo-cameos which were expected to go over the younger viewers' heads.

These jokes also give the shows rerun value years later when the original viewers are old enough to get the jokes that once went over their heads: see Late to The Punchline.Might be Fridge Horror for some if they think the joke is disturbing.

Contrary to the title, children of a certain age can get Parental Bonuses, most of them just don't watch shows that use them. (With the exception of SpongeBob SquarePants.)

A Super-Trope to Parent Service.

Anime

 * An early example, Maicchingu Machiko Sensei (Humiliated Professor Machiko) was infamous for having the titular teacher end up naked in every single episode, often as a direct cause of her students groping her or otherwise destroying her clothing. Maicchingu Machiko Sensei was a kids show, and her students were 6 years old. It was so prevalent that she even turns up naked in the episode openings. Twice.
 * Lots of these are present in Kirby of the Stars, since the series has tons of Shout Outs in general.

Comic Books

 * In one issue of Gold Key's Pink Panther, the titular feline finds a laundry bag filled with money. "I've heard of filthy lucre, but I never knew it needed to be laundered!"
 * Marvel Comics' All-Ages title Marvel Adventures loves referencing older comics, concepts, and complex storylines that the target audience is generally completely ignorant of.
 * Marvel Adventures: Avengers 24 sneaks in a Simpsons ref, a "reverse-Napoleon complex", Spidey "needs a wife", Wolverine quoting Rorschach, and a surprising hint of Les Yay. In one comic.
 * Tiny Titans, a non-canonical comics series for kids featuring many of the younger superheroes/sidekicks from the DC Universe as young children, is obviously aimed at young kids. However, the many, many references to either storylines from the "grown-up" books (such as the Battle for the Cowl, when they fight a cow that stole Batman's cape and cowl, or when Darkseid is their substitute teacher and gives them a surprise exam, which they pronounce a finals crisis!) and other media aimed at adults (such as the first two rules of Pet Club being "you do not talk about Pet Club" and "you do not talk about Pet Club") prove they were intended to be entertaining for parents as well. And they certainly are.
 * Calvin and Hobbes is full of this. Since Calvin has an unusually large vocabulary for a six-year-old and tends to discuss complex philosophy, reading the strip as a child and as an adult are completely different experiences.
 * Tintin features typical slapstick gags and exciting adventures children will appreciate. Adults can enjoy it for the satire on 20th century politics, exquisite story structures and beautiful art.
 * Asterix has a lot of general slapstick, running gags and situation comedy that both parents and children can enjoy. But it is as much a comic for adults as it is for children, with many puns, double entendres,satirical gags, cameos and references to classic literature, the Ancient Greek, Roman and Gaulish time period, francophone culture and 20th century society.
 * Nero shares both jokes that children can enjoy as references to national and international politics and that were current when the stories were published in the newspapers.
 * Suske en Wiske is a children's comic that originally made a lot of jokes about Flemish-Belgian politics that only adults would get. Later most of them were removed from the later reprints, though occasionely some of them are still present.

Film
"Eddie (singing): I'm through with taking falls / and bouncing off the walls / Without that gun, I'd have some fun / I'd kick you in the... (falling vase hits him on the head)
 * If you think really hard, there is a parental bonus in the theme that the villains in the Home Alone film series use for their names. "Wet Bandits"? "Sticky Bandits"?
 * Used in all of the Shrek films. For example, in the first one, Shrek sees Lord Farquaad's towering castle and remarks, "Do you think he's Compensating for Something?"
 * There are many references to University of Notre Dame in the movie as a handful of the people that produced the movie were "Domers" (Notre Dame graduates). The biggest example being the shape of the castle, which is exactly like that of the Hesburgh Library. Another reference is the town of "Du Lac"; the University's name is University of Notre Dame du Lac, which refers to Mary, Our Lady of the Lake. The student guide/disciplinary manual is also called Du Lac. A third reference is Lord Farquaad. There are many quads on the ND campus, and there is a dorm that is in the middle of nowhere, i.e. on a "far quad". You can also see the outline of the famous golden dome of the university on the back of Shrek's vest.
 * "Farquaad" was also used as a way of getting as close as possible to fuckwad.
 * More relevantly, Shrek 2 has literally dozens of movie and TV refs, only a handful of which are going to be known to the kids. (The "Knights" show was a parody of Cops (series)) The refs go back as far as the original B&W "Frankenstein".
 * Shrek 2 also had a bevy of modern pop culture references that would go over kids' heads: the best is the people running away from the Gingerbread Man who run out of one Starbucks Farbucks and into another Farbucks across the street.
 * And of course, the chase involving Donkey being referred to as a "White Bronco".
 * Please keep off of the grass. Shine your shoes. Wipe your....face.
 * Robin Hood's song "I like an honest fight and a saucy little maid / What he's basically saying is he likes to get laid -paid!
 * Blink and you'll miss it, but as the Fairy Godmother rattles off her list of fairy tales, she slips Pretty Woman in there.
 * Disney's Aladdin, thanks largely to the comedic genius of Robin Williams, works on every level humanly imaginable. Specific example: as the Genie is being tricked into getting Aladdin out of the cave, he gets very angry at Aladdin. Kids laugh because of his sarcastic tone and the ruse working; parents laugh because the speech is almost directly lifted from Taxi Driver. Kids are also unlikely to recognize the Genie's imitations of William F. Buckley, Peter Lorre, Carol Channing, Groucho Marx...
 * Aladdin's introduction scene also had what might have been a Les Miserables reference.
 * There's a moment during the song "Never Had a Friend Like Me". During the song the Genie uses his magic to make a group of harem girls appear. Normally this would be (somewhat) harmless but when you consider both the way the girls were acting towards Aladdin and how Al himself reacted it seemed like one of the girls (the one in the middle to be exact) was giving Al a freaking lap dance. In addition the way Aladdin's hands are positioned it looks like he's groping the girl's ass, the scene in question is in 1:45-1:53. Could be viewed as Parent Service.
 * There's also a specific comment by Genie during Aladdin and the King of Thieves during the beginning of the scene where the infamous 40 Thieves rob the palace. When the stampeding elephants come towards the wedding which causes the ground to shake, Genie jokingly comments "I thought the earth shaking didn't start until the Honeymoon" you can guess what that means.
 * The line is even worse in the Finnish dub, which changes "honeymoon" to "marriage bed".
 * Genie makes a ton of references from old movies: Poltergeist, Alice in Wonderland (obvious), RoboCop... anyone else recognize the big blue robot as the ED-209?
 * He even references The Tale of One Thousand and One Nights with the first line in his intro song; "Ali Baba had them forty thieves, Scheherezade had a thousand tales". What's funny (and rather sad) is that most kids - or even adults - wouldn't register that both Aladdin and Ali Baba are stories that Scheherezade told during those one thousand and one nights.
 * "Arabian nights, like Arabian days, more often than not, hot, hotter than hot, in a lot of good ways."
 * In Hercules, Herc and Megara see the play Oedipus Rex. Hercules only had one thing to say about that: "And I thought I had problems."
 * Also a Basic Instinct reference. Megara talks about having weak ankles, uncrosses and recrosses her legs, and says, "Do you have a problem with this?... weak ankles, I mean."
 * Although this joke wasn't sexual, when Pain and Panic (disguised as children) are "trapped" underneath the giant rock, one of them yells, "Someone call IXII!"--the Roman numerals for 911.
 * And then there was the sundial salesman...
 * And Herc making sure to get a good look at Nessus' (a centaur's) body before calling him a 'sir'...
 * In Beauty and the Beast, the wardrobe says "Let me see what I have in my drawers" and then a bunch of underwear flies out. The double meaning of drawers is sometimes completely lost on kids.
 * Not to mention Lost in Translation.
 * The "patty cake" scene from Who Framed Roger Rabbit? is a double subversion.
 * There's plenty more where that came from. Dolores' line about having to "shake the weasels", for instance.
 * "Dabbling in watercolors, Eddie?"
 * Who Framed Roger Rabbit? is one of the kings of this trope.

Roger: ...nose!

Smartass: Nose? That don't rhyme with 'walls'.

Eddie: No, but this does! * kicks him in the groin*"

"Cruella: Well, what can I say? Accidents will happen.
 * "Nice booby trap."
 * The weasel's screaming in that scene allegedly translates as "Shit, my fucking hand!"
 * Not to mention Jessica's breasts making boinging sounds twice when she visits Eddie's office.
 * There's a scene where Eddie fires some Toon bullets at a fleeing assailant, who ducks down an alleyway. The bullets stop, wonder "which way did he go?", and proceed to go in the wrong direction. Eddy comments "Dum-dums!"
 * Enchanted has quite a bit of this as well.
 * The Cat in the Hat movie attempted this, with questionable results. Apparently, the writers' idea of Parental Bonuses are almost PG-13 level double entendres; see here.
 * In the Jim Carrey version of How the Grinch Stole Christmas, the Grinch as a young boy looks in at a Christmas party where people are dropping keys into a fishbowl; indicating this was a swingers party.
 * Seconds before the keys are dropped into the fishbowl, a pair of Whos walk across the window, a man giving a woman a * ahem* "Reverse Piggy Backride".
 * In another scene, babies fall from the sky in baskets with umbrellas, a variant upon the Stork myth. A man sees a baby outside his own house, and joyously shouts to his wife that the baby is here, only to realize "He looks just like your boss..."
 * Madagascar has a Twilight Zone joke ("It's a cookbook!"), a Planet of the Apes joke ("You had it all and you burned it up! Darn you! Darn you all to heck!"), and an American Beauty joke (Rose petal scene vs. steak scene).
 * Plus a Moulin Rouge reference right before the characters are shipped off to Africa.
 * Not to mention a Cast Away joke. "Shut up, Spalding!"
 * The sequel has a great one near the end: "Ramming speed!!"
 * The Hunchback of Notre Dame has a character say to his horse "Achilles. Heel." Think about that for a second.
 * One Hundred and One Dalmatians (Live Action Adaptation): Roger tells Cruella that Anita is pregnant...

Roger: We're having puppies, too.

Cruella: (gasps) Puppies! You have been a busy boy!"

"Anita: But where did they all come from?
 * To say nothing about this little exchange in the cartoon, after Pongo and Perdita return with the 99 puppies...

Roger: Oh, Pongo-boy, you old rascal!"

" Gurgle : Do you guys realize we are swimming in our own sh-
 * Come to think of it, every Pixar film has plenty of these.
 * In Finding Nemo:

Peaches : Sh! Here he comes!"

" Snowman : Care for a snow-cone?
 * At the end of Toy Story 2, Buzz is having a hard time talking to Jesse. She does a skateboard stunt using a Hot Wheels car and track, and his fold-out wings pop out. Does This Remind You of Anything??
 * This certainly gives a new meaning to the "This Space For Rent" joke during the outtakes.
 * And in the original movie, there's the line about Woody having "laser envy".
 * One of the very first scenes in the first movie is Slinky going on and on with his speech about how Woody is right and everyone should listen to Woody. Mr. Potato-Head takes off his mouth and taps it against his backside to visually suggest Slinky is an ass-kisser.
 * Bo Peep throws out a few; in the first, she suggests to Woody that she get "someone else to watch the sheep tonight", and in the second she gives Buzz a kiss, telling him to give it to Woody when they find him. Buzz says he doesn't think it'll have quite the same significance to Woody coming from him instead of Bo.
 * Monsters, Inc. gets two for the price of one. The Abominable Snowman is clearly a riff on the "Bumble" from the Rankin/Bass Productions Rudolph the Red-Nosed Reindeer special, and also scores an extra for this exchange between himself and Mike:

Mike : Eccchh!

Snowman : Oh, don't worry. It's lemon."

"Fly: Hey, cutie! You wanna pollinate with a real bug?"
 * Combined with an Actor Allusion, when the character voiced by Steve Buscemi threatens to put another character through the shredder.
 * In Ratatouille, during Linguini's flabbergasted attempt to reveal his secret (that his cooking skills are actually thanks to a rat's instructions) to Colette, the moment that he says that he has a "...tiny, little..." she takes a split-second glance downwards.
 * Not to mention when she mentions to the press that he calls his inspiration his "little chef". His reaction shows that they were clearly not on the same thought pattern there as he tries to hush her about keeping private things private.
 * WALL-E has about five dozen 2001: A Space Odyssey references.
 * Also, "Stay The Course"
 * A Bugs Life, in the carnival scene...

" Gibbs : The Black Spot!
 * If you pay attention to the very beginning of Cars, you'll notice the two red Miatas flashing their headlights at Lightning McQueen.
 * Lightning McQueen's name, in and of itself, qualifies. The target demographic of the film won't know who Steve McQueen is, much less have seen Bullitt.
 * At the end of the first race mcqueen is talking to the rusteez representative explaining why he doesn't have head lights. Mcqueen: Well, you know, race cars don't need headlights, because the track is always lit. Dusty Rust-eze: Well, so is my brother, but he still needs headlights!
 * Lightning's rival Strip "The King" Weathers is an even bigger one: The car is a near replica of Richard Petty's racecar, he shares the same nickname and number of championships as Petty, and the spinning crash in the final race is a Shout Out to the one Petty suffered in the 1988 Daytona 500. Oh yeah, and Petty actually provided the voice.
 * The Cameo from the hosts of the radio show "Car Talk".
 * Towards the end McQueen has a wonderful exchange with his agent in one of the most fascinating Actor Allusion and Parental Bonus ever. If you still don't get or remember why it is absolutely hilarious take a look at this clip and this sound clip from Cars (sorry couldn't find the video).
 * What about the scene in The Incredibles where Syndrome has everybody then realizes that Mr. Incredible and Elastigirl are together. It culminates with him looking at the kids and adding "and got busy!"
 * In Flushed Away a fridge is lifted at one point to reveal a cockroach casually reading. And what is he reading? Why, Franz Kafka's The Metamorphosis of course!
 * Aardman in general loves Parental Bonuses. Their finest example is probably Chicken Run; if it's a World War II prison escape/action film and is pretty well known, Chicken Run probably includes a clever Shout-Out to it. Even the score gets into the act.
 * In Willy Wonka and the Chocolate Factory, as Willy Wonka searches for the button on the Three-Course-Dinner Gum machine, he offhandedly asks "Button, button, who's got the button?"
 * Dexters Laboratory pulls a similar joke when Dee Dee is, of course, left standing next to a button unattended.
 * Pirates of the Caribbean: Dead Man's Chest has a deliciously subtle one when Tia Dalma finds the Black Spot (an omen of death) in Jack Sparrow's palm:

Ragetti : The Black Spot!

Pintel : Black Spot!

Jack Sparrow : My eyesight's as good as ever, just so you know."

"Woman on Plane tells Shaggy her name is Mary-Jane.
 * Which is a very roundabout way of making a connection between palm sores, masturbation, and the myth that it causes blindness.
 * It's also an indicator of syphilis (which Johnny Depp has more or less confirmed Sparrow as having, probably a contributor to his eccentric nature), which can damage eyesight.
 * There's a very subtle one in the same movie. The sailors going on the Flying Dutchmen chant "Pull out your eyes, Apologize, Apologize". Any James Joyce reader will recognize this from Dante's introduction in A Portrait of the Artist As A Young Man
 * The Scooby Doo Movie had one that is very easy to miss out on:

Shaggy: Mary-Jane? That's my favorite name!"

"Buster: I can't marry all three of them, that's bigamy!
 * For those who don't get it, Mary-Jane was an old-timey slang term for marijuana.
 * The "hot box" scene. Soon after the team "breaks up" at the start of the movie, the following scene shows the Mystery Van with a whole lot of white smoke billowing out of it. Cut to inside, and you see that Shaggy and Scooby simply have a miniature barbecue that is letting off a lot of smoke.
 * In Homeward Bound: The Incredible Journey, Chance the dog is chewing a shoe and offers a piece to Sassy the cat. She replies "No thanks, I'm not into leather".
 * In Homeward Bound: Lost in San Francisco:, Sassy wakes up and finds herself laying next to that runt dog with fleas. Sassy recoils in disgust and says, "Yuck!" The dog responds, "That's not what you said last night!"
 * Tiny Toon Adventures How I Spent My Vacation:

Big Daddy Boo: No, that's big 'a me!


 * Which is itself a direct lift of an old Marx Brothers joke (from Animal Crackers, specifically)."

"Dorothy: We've brought you the broomstick of the Wicked Witch of the West. We melted her.
 * Non-joke example: In The Monster Squad, after the kids have been to Scary German Guy's place and he turns out to be quite the good guy despite his scary exterior, the leader of the titular group mentions that he "sure knows a lot about monsters." Scary German Guy's response: "Now that you mention it...I suppose I do." And as the kids leave, we're shown a reveal on Scary German Guy's arm of a numbered tattoo that the adults of the audience will recognize as a concentration camp identification tattoo, signifying that this guy indeed knows a great deal about monsters.
 * In Fred Claus, Santa demonstrates the power of the snow globe to his brother, Fred, who's visiting some part-time work. Fred then asks if he could use it to check on the Swedish Women's Swimming Team, to check if they were doing anything "naughty".
 * From G-Force: "Yippe-ki-yay, coffeemaker!"
 * Plus:
 * Dogs! Why did it have to be dogs!
 * One of the reasons Shark Tale failed with critics was because it was so overloaded with references to adult gangster films that they couldn't see how it would appeal to children.However, the chances of an adult understanding all the references is still slight.
 * Space Jam had a little Pulp Fiction reference in the end basketball game...
 * A Goofy Movie has Goofy mentioning mambo king Xavier Cugat, a relatively obscure reference for such a movie.
 * The Wizard of Oz had many lines what would be funny to adults but not children.

Wizard: You liquidated her, eh?"

"The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side."
 * The line spouted by the Scarecrow when he received the Th.D. degree, which was a hashed up version of the Pythagorean Theorem:

"Scarecrow: I've got a brain! How can I ever thank you enough?
 * The wizard awarding the Lion a medal called the Triple Cross.
 * The Scarecrow and the Wizard:

Wizard: Well, you can't."

"Scarecrow: Of course some people do go both ways."
 * The Scarecrow to Dorothy

"Charlie: Woah! You're flying!
 * The Santa Clause has quite a few of these. One example is when Scott picks up Santa's bag and he's lifted into the air:

Scott: It's okay, I'm used to it. I lived through the 60's."

"Bernard: It's... Charlie.
 * Speaking of druggie-references, in its sequel, The Santa Clause 2, Santa Claus/Scott Calvin and Bernard, when learning about Charlie's addition to the Naughty List, gives this exchange:

Scott: Sheen? I thought he straightened out."


 * It also goes into Harsher in Hindsight, considering the kinds of stuff he's doing by 2011.
 * Rango, among several other references, has a short scene in the beginning of the movie where the protagonist lizard Rango (voiced by Johnny Depp) crashes into the windshield of a red sportscar with in it two characters that are unmistakably Raoul Duke (also Johnny Depp) and his attorney from Fear and Loathing in Las Vegas.
 * The productions of Illumination Entertainment seems to love referencing the outgoing global economic crisis, as the former references Lehman Brothers while the latter mentions the book (and eventual movie) Too Big To Fail.

Literature

 * A Wrinkle in Time and its sequels feature numerous plot devices to get the characters to travel in space and time and even into their own bodies, most of which are based on real scientific concepts. This makes reading them as a kid and as an adult two very different experiences.
 * That's more a case of Shown Their Work.
 * In The Wonderful Wizard of Oz, courage takes the form of a liquid. Or, at least, the kind of courage that "makes you forget you are afraid" does. Or so the Wizard claims.
 * An in-canon example occurs in one of the Amber Brown books, which are written specifically for elementary-school kids. When Amber, her mom, and her mom's boyfriend are about to start baking, Amber claps her hands and goes "Alright, let's start some preheating!" Her mom and Max look at each other, laugh, and refuse to explain. Amber narrates how annoying that is.
 * A Series of Unfortunate Events. By. The. Truckload. Just a few examples off the top of my head:
 * 99% of the characters' names are literary references, especially the inhabitants of the island in The End.
 * Mr. Poe had two sons named Edgar and Albert. Just guess that one.
 * Similarly, the two Quagmire triplets that the Baudelaires meet first are named Isadora and Duncan.
 * Not to mention the Baudelaires, two of whom are named Sunny and Klaus
 * In The Reptile Room, the Baudelaires are told not to let the Virginian Wolfsnake near a typewriter.
 * The whole plot of The End is one big Bible reference/commentary.
 * Two of the island's inhabitants were named Dr. Kurtz and Ms. Marlowe.
 * The titular festival of The Carnivorous Carnival is called Caligari Carnival.
 * Louise Rennison's Withering Tights, a 2010 novel aimed at 14-year-old girls, has a scene that's a mashup of An American Werewolf in London, Withnail and I, and the Monty Python's Flying Circus milkman sketch (the "some of them are very old" punchline is identical).
 * In the Rainbow Magic series (for girls under 10 years old), the king and queen of Fairyland are named Oberon and Titania, the names of the fairy king and queen in A Midsummer Nights Dream.

Live Action TV
"Count von Count: Ah-ha-ha! I am the best counter since Formica!"
 * Speaking of Sesame Street, try to think of a Muppet production that doesn't include these. We'll wait.
 * In particular, The Muppet Show almost always did Actor Allusions about their current guest stars.
 * And then there's the episode in which Miss Piggy sings an old music hall song about a woman left at the altar by her fiance, dressed for the occasion in a wedding dress with a large pillow shoved up the front. The significance of the abandoned bride's expanded waistline is left for the viewer to fill in.
 * Jim Henson would have said that the Muppet Show wasn't aimed at kids in the first place.
 * Most of the sketches in Sesame Street had slapstick and word-play for the kids, with parody as the Parental Bonus. And occasionally even some wordplay that was clearly not for the kids:

""...The dialogue is sharp-edged, witty, and thematically skewed to adults.""
 * Sesame Street once did a parody of Waiting for Godot. After a while, the tree walked out because it was too confusing.
 * Another Sesame Street parody had a couple's car break down, forcing them to run through the rain to the door of a castle. The couple? Count von Count...and Susan Sarandon.
 * How about Katy Perry's sketch on Sesame Street with the naughty dress parodying "Hot and Cold"?
 * Will Arnett was on an episode doing illusions.
 * Similarly, Fraggle Rock played hard and fast with parody and social satire. One episode, for example, depicted a villain trying to take over the Rock with a very direct reference to Pink Floyd's The Wall.
 * It has been argued that Sesame Street owes its success to "entertaining the parents so much they forced the kids to watch."
 * They even did a parody of the Old Man Spice Commercial "The Man Your Man Could Smell Like", teaching kids the word "on". It even skips "The tickets are now diamonds" with the clam biting Grover's nose. At the end, Grover says, "I'm on a horse!" but it is a cow, and he corrects himself after the cow moos.
 * They did one teaching about the letter M...via a Law and Order: SVU parody.
 * Dinosaurs, another show from the Jim Henson Company, also does this. And is even Lampshaded in this scene. Complete with Aside Glance.


 * The Ghostwriter episode "Am I Blue?" was an homage to Star Trek fandom. Another episode had flashback scenes that resembled 1930s film noir.
 * The absolute king of this trope was Square One TV, which had an average of a Parental Bonus a minute. Sketches parodied everything from Max Headroom to Pac-Man, and the musical numbers were always a style spoof (like the country-western "Nine, Nine, Nine" or the glam-rock "Angle Dance"). Each episode ended with a mystery called "Mathnet," an elaborate (and sometimes disturbingly true-to-form) parody of Dragnet, where agent Kate Monday (later changed to Pat Tuesday) flashed her calculator as a badge. In one "Mathnet" sequence, we hear a voice over an airport intercom: "Will Miss Amelia Earhart please come to the front? Miss Earhart, we have your luggage."
 * Mathnet has a large enough Peripheral Demographic that it was shown as a stand-along program during primetime.
 * Not to mention the music video that started with some teenage girls noticing that their friend's relationship must've gotten serious as they saw a "diagram" in her purse... That one might actually qualify as Getting Crap Past the Radar.
 * The Electric Company was full of these, most notably "Easy Reader" and "Fargo North: Decoder".
 * The 2009 remake is full of these too, at seen in the pilot episode running on PBS. There was a character named Rebus wearing a shirt with "RE + " and a picture of a bus (does that count as a meta-rebus?), a sketch involving a dog known as Jack Bowser, and several references to the original series.
 * Some of the songs were done by Tom Lehrer, who thankfully refrained from some of his better known works like Wernher von Braun, The Old Dope Peddler and I Hold Your Hand in Mine (which he has had requests from adults not to perform). There were still a few Parental Bonuses in his Electric Company songs, though.
 * Beakmans World delights in old-school Parental Bonus references, which most frequently pop up in the Beakmania introduction, where every dance referenced by Beakman is an actual dance.
 * One episode of Zoobilee Zoo was a direct parody of My Fair Lady.
 * In Hannah Montana, the father (played by Billy Ray Cyrus) is often heard saying things like, "Oh, my achy-breaky back!" He and other characters also frequently mock his former mullet hairstyle.
 * Also notable is the episode in which Miley pretends to be a Hannah Montana impersonator, where Billy's character Robbie Ray Stewart dons a mullet wig and introduces himself to a nosy reporter, saying "hi, I'm Billy Ray Cyrus".
 * In the end video of the iCarly episode "iMeet Fred", one character sings "I buried Paul."
 * In the iStart a Fan War episode, Jack Black's character recites the Charm of Making from Excalibur.
 * In The Sarah Jane Adventures episode "Revenge of The Slitheen" Maria's divorced mother asks her ex-husband if she can have the double bed size duvet as he won't need it having a single bed. Her mannerisms and delivery of this line is enough to make older viewers think she's making fun of his sex life.
 * Continuity Nods to Doctor Who (new and classic) and Torchwood also count.
 * "Love and Monsters". A man and an animated concrete slab containing a talking head have a "bit of a love life". Figure that out for yourself.
 * As RTD put it, it was "good old-fashioned British smut".
 * And in Tooth and Claw, "The servants were all bald men in suits and your wife was away... I thought you were just happy."
 * In "The Doctor Dances", the Ninth Doctor switches Jack's sonic blaster with a banana without Jack catching on. Funny enough on it's own, but funnier for those parents that recognize the joke from the Buster Keaton short "The High Sign".
 * Pee Wees Playhouse was loaded with enough of this that it was resurrected... on Adult Swim. Watch any episode with Miss Yvonne and you'll come across some.
 * The show's original run was so popular with adults that a few episodes were broadcast during primetime.
 * This is referenced within The Office. Michael brings in a tape from a kids show he was on. There's an interview segment with a cat puppet called Edward R. Meow. While most of the staff laughs and notes that it's clever, Michael still doesn't get it.
 * Rainbow once played this trope for laughs: . Sadly, this was a gag episode that was never intended to be viewed by children, but it's still hilarious.
 * In an episode of Suite Life On Deck, Woody sees London's rich friend and says "She's hot. Does she have any interest in "woodworking"?
 * LazyTown. Just LazyTown.
 * In Balamory PC Plum often sings a song that starts off as a parody of Gilbert and Sullivan, and ends up as a parody of Bohemian Rhapsody
 * Power Rangers RPM had a non-sexual example in the fact that the planet had been razed in a nuclear holocaust. They outright showed that it was razed, but only the parents would connect the dots on the clues that Venjix had used nukes.
 * Power Rangers has slipped in a few (not really for parents, but for older fans.) In Dino Thunder, one character uses the phrase "ankle biter," a bit of Aussie slang for a small child. The only people who got that joke are the older fans who know that the show has been filmed in New Zealand since 2003.
 * Mister Rogers Neighborhood included a puppet named Donkey Hodie who lived in a windmill.
 * Horrible Histories has plenty of these. How many kids are going to realise that the Dick Turpin song is one big pastiche of Adam and the Ants Stand and Deliver?
 * In fact, there was enough Parental Bonus that it made the leap from CBBC to prime-time BBC One (with Stephen Fry as presenter).
 * Referenced in "How I met your mother" in an episode where we see the children's TV Robin starred in as a teenager. It's wall to wall sex jokes, including the song "Two beavers are better than one.".

Music

 * The Wiggles, an Australian children's music group, has done covers of songs by The Beatles. Including 'Octopus's Garden', fittingly as one of their mascots is Henry the Octopus.
 * Not to mention they have a song called "The Clap."
 * Sadly, the Wiggles did not actually sing "The Clap." It's a spoof of the Wiggles by a group calling themselves "The Giggles."
 * The Bedrock song. Oh, the Bedrock song. Michael Jackson, Stevie Wonder, and (of course) The Flintstones, for parental bonuses in rap songs, this takes the cake. In this case it's not really intended for kids, but teens, but still counts because most parents are forced to listen to the music their teenagers play when they travel in the car.

Theme Parks

 * At Disney Theme Parks, many places serve alcoholic beverages for adults. In fact, Drinking Around the World is a popular activity for older guests at EPCOT.
 * This happens the third version of the Disney World ride Journey Into Imagination in the smell lab. A slot machine is seen, and it rolls to reveal 3 Figments dressed as skunks. Then, they all say "Congratulations! You win one scent!", and Figment releases an unexpected aroma.
 * Yeah, why would they have a slot machine on a ride intended for toddlers in the first place?

Video Games
"Carmelita: FREEZE!
 * General Pepper from the Star Fox series. Think about it. If you don't get it, here's another clue for you all: in the Star Fox comic in Nintendo Power, Fara asks why Pepper didn't do something. His answer? "I was only a sergeant then..."
 * Did anyone mention Earthbound yet? The Beatles references never end: the Runaway Five, a yellow submarine, and a set of default names for Ness & co.
 * A couple more: when Nessie takes Jeff across the lake, the musical score is very obviously the opening mellotron from Strawberry Fields Forever. Also, one of the NPC's in Onett will ask you to "Finish this famous Beatles song ---terday" with a yes or no prompt.
 * On the topic on the Runaway Five, not only is the design of the lead singers reminiscent of the Blues Brothers, but a certain hotel newspaper (as reported by the bellboy) claims that band member Lucky (modeled after Jake Blues, played by John Belushi) was seen in congress, an elaborate reference to John Belushi's role as John "Bluto" Blutarsky in National Lampoon's Animal House, in which the aforementioned character goes on to become a senator.
 * Oh, and the New Age Retro Hippie's theme sounds a lot like Chuck Berry's "Johnny B. Goode." As does Rockin' K.K. from Animal Crossing.
 * No one can forget Peaceful Rest Valley- or should I say, Grateful Dead Valley. Home to a strange cult in a familiar outfit, with a strange obsession with the power of a certain color....
 * The Happy Happy Cult can be taken two ways: either as a reference to Blue Meanies, or the KKK. Or both.
 * One of the enemies is called Diamond Dog.
 * The Dungeon Man's theme, after he joins your party, is based on 'Sgt. Pepper's Lonely Hearts Club Band'.
 * The music that plays when Jeff rides in the Sky Runner is taken from a song by The Who.
 * The thing with Earthbound is that these are less likely to be intended as a Parental Bonus, so much as being thrown in because those involved (mainly Shigesato Itoi and the composers) really, really liked this stuff (the entire franchise is specifically named after a Beatles song, for god's sake!).
 * Paper Mario: The Thousand-Year Door was just loaded with somewhat suggestive material, to the point that it's a wonder they managed to get such low age ratings. It got a 3+  rating in Europe and an E rating in North America (the "E-10+ " rating didn't exist at the time).
 * Including a nude scene for Princess Peach..
 * Goombella was a walking Parental Bonus as well. Many of her tattle-analyses did this (or broke the fourth wall). Oh, and the Goomba-Gang that tried to hit on her plays real nice.
 * Then there's Fahr Outpost, a snowy region populated by bombs who wear bearskin hats. Their mayor speaks broken English peppered with 'da's and vehemently denies the existence of a superweapon on the base.
 * The official Nintendo Player's Guide actually lampshaded this: "Considering most of the Bob-ombs speak with Russian accents, those of you who grew up in the '60s may feel a bit nervous when you see the enormous weapon rise from a silo. Resist the urge to hide under a desk and tuck your head between your legs."
 * Among the less radar-dodging examples, the whole of Chapter 6 is a spoof of English detective novels and one of the supporting characters from Chapter 5 is a pirate named Cortez.
 * The Battalion Wars series of games is chock-full of references to nearly everything under the sun.
 * The countries are The Theme Park Version of real countries:
 * Western Frontier: (Cold War U.S.A.), overanxious, obsessed with sports, ever vigilant of the Tundran Bear, led by a man named Herman.
 * Tundran Territories (Cold War U.S.S.R.): red uniforms and armour, vehicles look thrown together, condemns Frontier decadence.
 * Solar Empire (Japan): Better technology than anyone else, like quoting Sun tzu, fight for honour.
 * Anglo Isles (Great Britain): Use yellow Sgt. Pepper-class submarines, one of their leaders is named Windsor.
 * Xylvania: Full of German and vaguely German accents, a nation determined to return to power after a defeat.
 * Kommandant Ubel of Xylvania is a muscle-bound thickhead with dreams of becoming "governator".
 * M17s, KA-74s, Humbugs, etc. in unit descriptions. Most of the Frontier units with names are references to a real-world American military vehicle of some kind.
 * Some of the mission names, like "Bridges over the River Styx", or Herman's Heroes.
 * Ape Escape. The third installment had movie-and-TV making as its conceit, so this involved parodic Homage Shots of such kid-friendly things as The Exorcist, Psycho, 2001: A Space Odyssey, Planet of the Apes, Apocalypse Now, Django, and Titanic (to name just a handful), as well as games parodying Mortal Kombat and Metal Gear. The names of the monkeys, in the UK localisation at least, often reference people in the movie industry (there's monkeys called M. Clayderman, D. Elfman, Ricky Ger V and Culkin, for just a handful of examples). Not only that, but some of the Simian Cinema shorts have a 'clean meaning' that the kids will find funny, and a 'dirty meaning' the older demographic will find funny (the one with the nude monkey telling the other nude monkey 'the ancient secret to keeping warm' before flossing between her legs with a towel as demonstration comes to mind).
 * The European website for the games is called Ape Club. Its logo is a bar of pink soap. One of the minigames on it explicitly asks you to 'Spank the monkey', although that might be Getting Crap Past the Radar.
 * Disney's Extreme Skate Adventure was a Mission Pack Sequel to THPS 4. Here's a few of Zerg's moves, word for word:
 * Remember, I Was Vapor
 * Pertinacious 'D'
 * Astro Glider
 * Humongous Entertainment. Oh boy, where to start? Pajama Sam's superhero references, Spy Foxs James Bond references, Backyard Sportss 80s references (most pros were kids then)...all more likely to grab parents than kids.
 * Some background animations in Pajama Sam: No Need To Hide When It's Dark Outside in the hallway filled with windows looking out into space. One of the windows, when clicked, shows a cheese floating by and a monotone voice says "I'm afraid I can't eat that cheese, Sam.", as well as the chair in the lab who spoke in lines that sounded like solutions from Clue.
 * Tell me Dmitri Petrovich doesn't look like Elton John.
 * One of the dragons in Spyro the Dragon informs him of his "density . . . I mean, destiny", an homage to George McFly's pathetic attempts to pitch woo in Back to The Future.
 * A minor character from the second game messes up an attempt to say 'Klaatu Barada Nikto Barada Nikto'.
 * Mysterio also says this in Spider Man 2 Enter Electro.
 * There's also a child-friendly homage to Doom in the third game.
 * The Crash Bandicoot series tends to aim its Shout Outs at older players. Apart from the fact that getting all the name jokes requires a GCSE-level understanding of everything from Victorian literature to thermodynamics, level titles in Warped include 'Tomb Wader', 'Area 51', and 'Eggipus Rex'.
 * Stephen Fry's narrations in Little Big Planet contain innuendo and jokes that children won't get. "Here you can choose how erect your piston is. No smirking back there." Also the fact that some of the Licensed DLC is usually from titles for higher ages such as Metal Gear Solid and God of War
 * Sly Cooper has little jokes and pickup lines tossed in that have steadily built the series' adult fanbase. Here's an example:

Sly: How can I freeze when my heart warms at the sight of you?"

Western Animation
"Mojo Jojo: That's all just well enough, because in reality there is only room enough in this world for one Mojo Jojo. One shall be the number of Mojo Jojos in the world, and the number of Mojo Jojos in the world shall be one. Two Mojo Jojos is too many, and three is right out!"
 * In the first episode of late-90s ABC cartoon Pepper Ann, the titular character goes into Abe's Mall (with a big statue of Abe Lincoln out front) to buy some pimple cream. The names of various shops in the mall float behind her, including "John Wilkes Photo Booth," "Getty's Burgers," "Four Score and Seven Year Pets," and "Civil Wear."
 * The BBC pre-school educational programme, Numberjacks, had a rather British example when Number 4 and 6 both caught The Dreaded Lurgi.
 * Between the Lions often bases musical numbers on songs well outside the experience of its target audience, such as a song about the importance of breakfast to the tune of "Roadhouse Blues".
 * The guy responsible for that show he did the same thing for Sesame Street with such numbers as "It's Hip to Be a Square."
 * The Sam and Max Freelance Police episode "Christmas Bloody Christmas" featured Sam and Max entering a prison shower room. Max sees a bar of soap on the ground, and bends over to pick it up, with a sign saying "Do not open until Xmas" over his rear-end.
 * Heck, the Sam and Max animated series practically flipped the normal ratio of Parental Bonuses to stuff kids might actually get. References to Apocalypse Now, Aliens, The Thing, Born Free, Moby Dick, A Sound of Thunder, and The Man Who Would Be King are just a few of the obvious ones. If it had debuted on Comedy Central, it might still be running today.
 * The Recess episode "The Library Kid" featured the gang cornering said Library Kid in the Philosophy section, with Gretchen calling out "Head her towards the existentialists; there's no exit over there," a reference to Sartre's play. The actual opening looks like an elementary school version of Hogan's Heroes.
 * More than half the humor in Recess requires a high-school level of education to notice, much less understand.
 * Then there's the episode that was a Homage to 2001: A Space Odyssey.
 * The titles of some episodes like "Kids in the Mist".
 * Recess: School's Out has lots of references to various things. Among them, Ms. Finster yelling, "Hey, teacher, leave those kids alone!", and the song "Green Tambourine" (sung by Robert Goulet, no less) playing over the end credits while the kids danced in front of a psychedelic background.
 * Ms. Grotke was reading Beowulf out loud. And just happened to be reading the part where Beowulf rips Grendel's arm off and begins beating him with it.
 * The Veggie Tales videos are chock full of the Homage type of Parental Bonus. For instance, "Josh and the Big Wall" features peas with French accents taunting Joshua from atop a wall. References to Madame Bovary, Gilligans Island, and The Grapes of Wrath are just as likely to go over the heads of younger viewers..
 * Actually, given the religious theme of Veggie Tales, The Grapes of Wrath bit is fairly likely to be a reference to the song The Battle Hymn of the Republic, which is the origin of that phrase. The phrase is used in the song to call to mind the themes of the first part of Isaiah 63 and several other places in the Bible that use similar imagery.
 * It's also a reference to the book, given that the episode features a family of bumpkin grapes as Expy Expies of the Joad family.
 * Jerry Lewis, famous for comedies dating back to the 1940s-60s, is mentioned, albeit briefly, in Madame Blueberry.
 * "I think we're gonna get letters about this."
 * In one of his silly songs, Larry the cucumber allows both a bank robber and a viking into his house and gives them each a cookie ("Because it's Christmas!"). He slams the door in the face of the guy from the IRS, complete with a Smug Smile.
 * Likewise, the episode of The Powerpuff Girls titled "Los Dos Mojos" included its own Holy Grail reference:

"Bubbles: He made us in his laboratory by accident!
 * Another episode referred to The Big Lebowski, when Professor Utonium laments a rug that "really tied the room together".
 * Hell, they once had The Mayor recite the "Strong Men Also Cry" speech, but replaced Bunny with Bellum.
 * And The Dude, Walter, and Donny were in the background shot of an episode of Foster's Home for Imaginary Friends. Craig McCracken is a huge fan of the movie.
 * His wife, Lauren Faust, apparently gets in on it too; My Little Pony Friendship Is Magic has equine versions of The Dude, Walter, Donny, and Jesus Quintana show up in the background at the local bowling alley.
 * PPG did an entire episode of Beatles references, "Meet the Beat Alls", which got an Emmy nomination.
 * At the end of that episode, Blossom tries out a quote of her own, fails, and dismisses it with "Oh, who cares? It's by some dumb old band anyway."
 * And in the movie, references to naughty words were stuck in, including an elongated sigh of 'Fffff...'
 * In the episode "Super Friends" the girls invite their new neighbor, a girl their age named Robin, over to their house, and they introduce her to Professor Utonium:

Professor: Well, what can I say?

Robin: Don't worry, Professor. I was an accident, too!

[Cue surprised look on the Professor's face]"

"Mitch: But it was an accident!
 * A similar joke occurred in the episode, "Gettin Twiggy With It" when Mitch Mitchelson, who lived in a trailer park with his grandma, takes the class hamster, Twiggy home and starts playing with her violently. When Blossom, Bubbles, and Buttercup catch him in the act:

Blossom: You're an accident!"

"Mindy: It burns! It burns!
 * Many sexual innuendo jokes relating to Ms. Bellum occur. One was when Ms. Bellum came into the Mayor's office while he was writing something. She leaned on his desk revealing a lot of her cleavage. He looks up and breaks his pencil, and exclaims "Pencil go snap!"
 * Series creator Craig McCracken was fond of classic rock references in general. Two examples off the top of my head: an episode entitled "Mr. Mojo's Rising", and in another Ace of The Gangrene Gang shouts "Billy! Don't be a hero!"
 * Perhaps the most explicit example is Ms. Bellum's address: 69 Yodelinda Valley Lane. It's prominently displayed on her mailbox in several episodes.
 * Someday we'll be as developed as you!
 * The Grim Adventures of Billy and Mandy did an entire episode parodying God Emperor of Dune, the fourth book in Frank Herbert's Dune series, with Mandy as the God Emperor, Grim as Moneo Atreides, and Billy as the frequently-cloned-and-replaced Duncan Idaho. Another episode featured a nod to the classic black-and-white Walt Disney short, The Skeleton Dance. Yet a third parodies the musical Little Shop of Horrors: Billy plays Seymour, bringing victims to the singing, brain-eating alien who stands in for Audrey Two. They also had a geriatric Dracula, who was quite obviously supposed to be Blacula . They also had an episode entitled "The Prank Call of Cthulhu Mythos."
 * Another episode obviously references the Hellraiser movies with "Pinhead" who has bowling pins sticking out of his head and a rubik's cube look-a-like summoning him.
 * The episode with the Beauty Pageant had "gom jabbar" among the Pageant contests.


 * When Mindy pulled her hand from the pain box, the judges said something along the lines of "that will cost her." Funny, because in the book"

"Billy: For a good time, call --
 * The show's full of them. Here's one where Billy reads an ad off of a cave wall.

Someone else: Stop reading that!"

"Malaria: What do you mean, you can tell when someone fakes?"
 * Valentine's Day. In general. For one, the end of Mandy's episode was apparently a Grease parody, and let's not forget Grim's.

"Mung: Fireworks...she used fireworks.
 * Hurter Monkey: Billy and Mandy get a helper monkey who sounds like Kevin Spacey and even paraphrases the "simple life" speech from Se7en.
 * There is also the occasional visit from Hoss Delgado, a parody of both Snake Plissken played by Kurt Russell in Escape from New York and Ash Williams played by Bruce Campbell in Evil Dead.
 * In the opening to the episode "Duck!," Grim dreams about being in his dream house with his dream wife. He suddenly realizes, and exclaims, that "this is not my beautiful house," and "you are not my beautiful wife!," and then wakes up to Billy saying "same as it ever was," repeatedly. This is a reference to the song "Once In a Lifetime" by Talking Heads, which had the lines as lyrics.
 * And the theme song that plays at the beginning of his dream is similar to that of The Munsters.
 * The whole show was a huge parental bonus, heck I doubt kids would realize what happens when Grim takes people away.
 * In one episode, character's were being made horribly ugly and paper bags were offered to the victims to place over their heads. The character offering the bags commented that he only had paper bags left because the plastic bags were in greater demand.
 * Chowder. For an example, in one episode, Endive wears mood fruit, fruit that changes color to reflect the wearers mood. I'm not sure, but I think the fact that most of the time, every part of it is a different colour means something...but I AM sure that when it changed to brown, which was acknowledged, HAS to mean something.
 * When Chowder learns how to write, they use a montage of pictures of him interacting with various letters. "R" is depicted as looming over him in a dark back alley, getting ready to do something that rhymes with "grape".
 * Truffles' snarky remarks towards her nearly dead relationship with her husband, Mung. During Panini for President, when the two were watching her on stage:

Truffles: Oh, I've completely forgotten fireworks existed.. (Different voice) ...in our marriage... (Normal voice, shocked) Who said that?!

This gag is repeated throughout the series, seen here in episode 103

Mung: Truffles, mind the shop. We need more spice!

Truffles: Well, I'm glad one of us finally acknowledged it."

"Mung (to Truffles, in a suggestive voice): Let's get cooking.
 * Another one occurred at the end of an episode where Mung and Truffles rekindle their romance.

(Mung and Truffles head offscreen)

Chowder: Mung! Where are you going? The kitchen's that way!"

"Teacher: Yakko, do you know how to conjugate?
 * Both Animaniacs and Eek the Cat have done parodies of Apocalypse Now. In the Animaniacs one, the Colonel Kurtz character was an out-of-control director, portrayed in No Celebrities Were Harmed style as Jerry Lewis. The episode also memorably concludes with the main characters casually running over a caterwauling Jim Morrison.
 * Animaniacs also had an episode where the Warners were out to buy their psychiatrist, Dr. Scratchensnif, a birthday present. One asks about buying something from store called Oedipus Rex, and another remarks, "Nah, his mother wouldn't like it."
 * A different store sold 'Freudian Slips'. "No, he makes his own."
 * Animaniacs was also famous for hiding vulgar jokes. At the beginning of the song Wakko's America, the Warner Siblings are playing a Jeopardy-style game show, wherein Wakko is asked how much he wants to wager on the daily double. He responds, "I'll blow the wad," eliciting surprised looks from Yakko and Dot.
 * A running gag was Yakko lampshading a Double Entendre by implying it was enough to get the show cancelled.

Yakko: Who, me? I've never even kissed a girl!

Teacher: No, no, it's easy. Here, I'll conjugate with you.

Yakko: (to camera) Goodnight, everybody!"

"The Warners open up a bust of Freud like a Pez dispenser.

Dr. Scratchensniff: Stop playing with my bust!

Yakko: ...Goodnight, everybody!"

"Baloney: What "cute girls"? Yakko, I don't know what you mean!
 * The best Yakko lampshading has to be during "Baloney And Friends" where Yakko expresses a preference for chasing after the just-exited "cute girls" (the "Princess of Props".)

Yakko: (to camera) There's a shocker!"

"Yakko: (dressed as a detective) Dot, look for prints.
 * And let's not forget how The Brain spoke exactly like Orson Welles.
 * "Yes, always."
 * A writer described that cartoon as "a $900,000 inside joke."
 * Not so much a parental bonus, but Maurice LaMarche (The Brain's voice actor) sent up the same famous Frozen Peas recording session in an episode of The Critic, throwing in fish stick advertisements into a videotaped living will. "They're even better when you're DEAD!"
 * Also, there was a THX-1138 reference in the intro chalkboard scene.
 * One episode of Pinky and The Brain was done entirely as a parody of The Third Man.
 * Another episode was done as a parody of The Prisoner.
 * There was actually a lot of No Celebrities Were Harmed - style casting in the show, ranging from the obvious (The Goodfeathers) to the easy-to-miss (Katie Kaboom's dad spoke like Jimmy Stewart).
 * The Warners parodied a World War 2 "good citizenship" film, where ladies donated their nylon pantyhose to be made into parachutes. Who came to pick up the huge barrel of nylons? J. Edgar Hoover.
 * One that surprisingly slipped past the censors:

Dot: (now carrying the musician Prince) I found Prince!

Yakko: No, no, no. Fingerprints.

(Prince puts on a wide grin)

Dot: (Beat) I don't think so. (Throws Prince out the window)"

"Beethoven: I am Ludwig von Beethoven! Vorld famous composer und pianist!
 * Then there was the time the Warners met Beethoven:

Yakko: (startled) You're a WHAT?

Beethoven: A PIANIST!

Yakko: * smooch* ...Good night everybody!

Beethoven: (confused) But that is vat I am! A pianist!

Yakko: I think we heard enough out of you.

[Yakko literally washes Beethoven's mouth with soap]"

"Hunter: Give me the bird!
 * "My bottom's all sore from romping."
 * Animaniacs also had the "Rita & Runt" sketches, which often parodied Broadway musicals (but of course; Rita was played by Bernadette Peters!). These are all far funnier after having seen the musicals being parodied.
 * Other characters got into the Broadway parody act. The Goodfeathers did Whole Plot References of West Side Story and Fiddler On the Roof, and the Warners once harassed a diminutive, egotistical composer who was a very thinly veiled parody of Andrew Lloyd Webber.
 * And then there's the Thanksgiving themed episode with a hunter and a turkey:

Yakko: We'd love to, really, but the Fox censors wouldn't allow it."

"Minerva Mink: All right. Give me the bird!
 * Repeated during an extended The Maltese Falcon parody:

Dot: We can't. This is a children's show."

"Didi: Stu! You'll never guess who's coming for dinner!
 * This one predates the Animaniacs by several decades, first appearing (probably) in a Babbit and Catstello cartoon from the late 40s. "If the Hayes Office would only let me, I'd give him the bird all right."
 * Not to mention the episode devoted to a pastiche of Gilbert and Sullivan, of all things.
 * There's also the episode where the trio ends up in Czarist Russia? They meet Rasputin, who has a toothache, and needs dental work. Yakko remarks, "looks like he needs a little anesthesia!" ... and the Czar's daughter comes out and hits Rasputin on the head with a mallet. Dot even says afterwards, "Obscure joke, ask your parents."
 * Of course, after Anastasia, this pun isn't so obscure anymore.
 * The episode "Hot, Bothered and Bedeviled," where the Warners ended up in Hell (but obviously they couldn't say that). When they meet the Devil and realize where they are, Wakko dashes for a spiral staircase, comes out on Earth, gathers up a snowball, and runs back down the stairs, only to watch it melt rapidly upon setting it down on the ground. "Boy, they were right! It didn't have a chance."
 * Hey Arnold used the phrase "Snowball's chance" repeatedly in the episode "Stinky Goes Hollywood".
 * By all accounts, children shouldn't see Raging Bull or Goodfellas yet one of the recurring segments was called Goodfeathers and usually homaged those types of movies.
 * Yakko, Wakko, and Dot are themselves a parental bonus since they are basically animated versions of the Marx Brothers. Yakko especially is an homage to Groucho Marx.
 * Rocky and Bullwinkle did this constantly, as did Jay Ward's other animated series, Hoppity Hooper and George of the Jungle, and Ken Snyder's Roger Ramjet. At times it seems like more of the jokes are for the parents than for the kids.
 * One definitely for the parents: Boris, wearing a metal mouse costume in his role as the Big Cheese, details his plan to take over whole U.S. of A. He holds up a book. The title? "Mice Kampf."
 * Bullwinkle would sometimes have entire plots that were parental bonuses. An entire episode could be spent spoofing college football or modern art. Bonus points for the jokes being nowadays both mature and dated. How many modern kids are gonna get a joke about the payola scandal?
 * Rugrats' popularity peak can be traced to its frequent use of the Parental Bonus.
 * The creepy doctor that Chuckie visits in named Dr. Lector.
 * In another episode, while the children are looking for one of the children's favourite toy, they open up a drawer full of favourite things, and start pulling things out. On the screen can be seen a photograph of a woman.
 * At the beginning of the home movies episode, when Stu starts showing an incredibly boring home movie, Didi's father picks up the phone and says "Hello, Dr. Kevorkian?"
 * One of my favorites comes from the episode in which Dr. Lipschitz visits:

Stu: Sidney Poitier?"

"Timmy: Oh magic eight-ball, will Mom and Dad come home early? "Titanic! Director's cut?!" They'll be there all night!"
 * In another episode, the babies are chased through a Multicultural Fair. Chuckie gets temporarily separated, and nearly trampled by Jewish dancers. When the others ask him what happened, all he can say is "The Hora! The Hora!". They finally make a stand with the help of some Scottish babies, who taunt the pursuers by lifting their kilts to show that they aren't wearing diapers.
 * In the episode "Give and Take", Chuckie cannot stop playing with Tommy's new inflatable toy, called "Boppo". Phil says: "A kid his age should be playing with his friends, not sittin' in his room Boppin' his Boppo!"
 * And the movies Grampa brought home one night, 'Reptar Come Home', 'Reptar Redux', and ... 'Lonely Space Vixens'
 * In one episode, Tommy goes through a naked phase, where he refuses to wear his clothes. After talking the twins into following suit, he looks down at Lil and says "Lil. Can I ask you a question?"
 * In the series All Grown Up, the episode titles were frequently references to pop-culture that was probably above the target-audience's head, but nearly all were easily relatable to the episode, anyway. The exception would be the episode "Wouldn't It Be Nice", an episode where several characters (including Susie and Angelica) pretend to be married, which only makes sense if you know the song. The odds on the target audience being familiar with the source material is slim.
 * Seriously....lip shitz (the bullSHIT psychologist...is called...lipschitz...you know...as in shit comes out of his mouth.
 * In the Time Travel episode of The Fairly Odd Parents, after Fairies In Black erased everyone's memories of events, the main characters were requested not to interfere in "the re-election of President McGovern". The show as a whole was saturated with an ever-increasing amount of Parental Bonus. The very first occasion would have to be way back when it was still on Oh Yeah Cartoons:

"Timmy's Dad: * Pushing Timmy out the door* And that's everything you need to know about where babies come from!
 * One that sticks out is 'Dads' obsession with Eggnog in every christmas episode.
 * There's an episode where Cosmo and Wanda lose their wands at the beach. In searching for them they find, among other things, Elvis and the Holy Grail.
 * Probably closer to Getting Crap Past the Radar, but this exchange in the episode where Timmy wishes his parents were superheroes:

Timmy: But what's the machine for?

Timmy's Dad: We'll tell you when you're older, son."

"Cleft (Timmy): Thanks, CC! You saved me!
 * The intersections in Fairy World almost always are the names of famous magicians (like the intersection of "David" and "Copperfield")
 * Adam West voices Catman (I can't remember the character's "real" name), who is obsessed with the role he played on a 60's live-action show; his attacks are punctuated with large on-screen sound effect bubbles. The character's name is Adam Westing
 * Jay Leno portrays the comic book superhero "The Crimson Chin"

Chin: No, Timmy. You saved me-- from myself! Boy, that was schmultzy. Who did you say writes my comic books?

Cleft: Some 40 year old guy who lives with his mom.

Chin: Any money in it?

Cleft: (points to his caption balloon) Lives with his mom."

"Wanda (after Cosmo slightly alters her hair color in a fight): I'm not a summer, I'm a winter!"
 * Jorgen von Strangle, the Schwarzenegger fairy (no, they didn't actually get ahold of the governator for the role).
 * Ben Stein plays a race of bland, boring, industrious pixies.
 * And just general grown-up friendly silliness

"Cosmo:I don't get it. If you're not married to her, why is she trying to kill you?"
 * And...

"Timmy Turner: I'm huge, I hurt people, and I'm misunderstood!
 * And...

Cosmo: Just like the IRS!"

"Wanda:Oh no, now he's evil AND a genius!
 * And don't forget:

Cosmo: Just like Dr. Phil!"

"Crocker: If he survives, it means fairy godparents! And if he dies, I have tenure!"
 * Then there was the first Wishology episode. The minute that Timmy's dad popped open his case full of "goodies", I was on the floor.
 * And in an early episode with Mr. Crocker, as he ponders a trap that will either reveal once and for all that Timmy has fairy godparents to save him, or leave him dead...

"Anti-Cosmo (sitting behind a glassed-in cell): Hello, Clarise!
 * The second episode with Anti-Cosmo has a Silence of the Lambs reference.

Wanda: Clarise?

Anti-Cosmo: So sorry, can't see a thing without my monocle."

"Dr. Drakken: Your Nana is one bad grand-mother--
 * Wishology trilogy, anyone? Matrix references like there is no tomorrow, along with The Lord of the Rings, Terminator Salvation, Back to the Future, Men in Black, Star Wars, Cast Away....
 * Rocko's Modern Life was thickly saturated with these; the creators throttled things down considerably for SpongeBob SquarePants. However, the latter's popularity put it on the Media Watchdog radar and as a result, it was subject to more controversy.
 * The most famous example is a restaurant called "Chokey Chicken". This one was caught, and later episodes changed the name to "Chewy Chicken".
 * In addition to practically being an entire show's worth of homage to Transformers Generation 1, Transformers Animated has a number of parental bonus moments.
 * The Autobot science team is composed of Wheeljack, whose face greatly resembles a roboticized version of a certain walrus-faced Myth Busters, and Perceptor, whose computerized voice resembles that of physicist Stephan Hawking.
 * Wheeljack wasn't intended to look like a Mythbuster. But how about Decepticon Air or Mission Accomplished?
 * Sentinel in "Predacons Rising" - "Don't just stand there with your pistons in your servos." Really now?
 * Any episode of The Tick. The show doesn't quite make sense when you watch it as a kid, but things such as the "Ottoman Empire" (a bunch of goons obsessed with furniture) work out for older audiences.
 * SpongeBob SquarePants, as mentioned earlier, is a particular user of this trope, culminating in The Movie ending with Spongebob defeating Plankton with The Power of Rock. The song? A parody of Twisted Sister's I Wanna Rock.
 * The sequence includes a closeup of shapely legs in fishnets
 * The surprise appearance of Nosferatu, "wormsign", the titular character's trousers discarding akin to an o-ring separation before his legs erupt into rocket exhaust plumes, etc.
 * Watch "Karate Island" and just try and find more than three jokes that aren't Parental Bonus.
 * Another referenced George Carlin's "Seven Words You Can Never Say on Television" routine.
 * Don't forget the episode "The Secret Box", where the secret that turned out to be in the box was a string. Come on, a string in a box in a Bikini Bottom?
 * Of course, though, the string
 * And then there's Plankton and his reviewing of "foreign exercise videos" for his cousin.
 * When Squidward has convinced Spongebob and Patrick to wait on his every whim, they move around his sun chair to various locations-- one is Too Sunny, one is Too Wet, and the one with a background of cancan dancers is "Toulouse-Lautrec"
 * The episode that begins with SpongeBob watching a dancing live-action sea anemone on his TV, with a goofy entranced look on his face, leaning toward the screen. When Gary comes in and meows at him, he immediately turns off the TV and comes up with a hasty excuse for what he was really watching.
 * The episode with the squeaky boots is a parody of Edgar Allan Poe's short story The Telltale Heart.
 * Let's see, there's Ned and the Needlefish, an obvious reference to Hootie and the Blowfish; an episode titled "Krabby Road", like The Beatles' album Abbey Road; the episode "Lost Mattress", where, at the end of the mattress shopping montage, Spongebob goes to reach for a switch in the dealer's hand, who closes it sharply and makes Spongebob laugh, a reference to Pretty Woman; and some episodes which feature court cases use the theme from The Peoples Court.
 * A musical bonus: In the episode where Patrick becomes smart when he switches his brain with brain coral, he mentions a clarinet piece by "Cornelius Bumpfish". Someone on the writing team must like Steely Dan, whose clarinetist was a man named Cornelius Bumpus.
 * In one episode, Patrick dressed in drag and Squidward called 'her' "his Rubenesque beauty".
 * "You're a man, Spongebob, and it's about time you acted like one. First, puff up your chest. Then, say 'tax exemption'. Now you must adopt a taste for free-form jazz."
 * Kim Possible was fond of this, too. In one episode, Ron announces "the first rule of chess club is: you do not talk about chess club."
 * What's the second rule of chess club?
 * You do NOT talk about chess club.
 * In another...

Kim Possible: Shut your mouth!

Dr. Drakken: I'm just talking about Nana.

Sadly, Kim did not answer "I can dig it.""

"Señor Senior Sr.: Junior, this is not a party! This is not a disco! This is not... fooling around!"
 * The exchange was, however, played out in full in a Shaft parody episode of Dexter's Laboratory between Dee Dee and a friend.
 * And in yet another:

"Kim Possible: Payback's the sitch!"
 * Okay kiddies, how many of you have seen Psycho? How about played Resident Evil or Splinter Cell? Because homage is payed to all of these in one episode or another.
 * And then there was this:

"Yin: Yang, where do you think Carl the Evil Cockroach has gone?
 * "Careful Bonnie, you know what they do to witches in this town." Given how she quickly hops away with a frightened look Bonnie guessed she was being a bitch.
 * How many people in Kim Possible's target demographic would recognize the character Ron is channeling in this screenshot?
 * Not to mention in the episode where they had to have mentors and Ron's happens to be a secret agent, Ron starts using a Scottish accent as a reference to Sean Connery as James Bond. This was exceptionally cool for older folks who always see Sean Connery as Bond rather than the more recent actors like Pierce Brosnan and Daniel Craig.
 * Yin Yang Yo has several, not the least of which is Yang saying "Ah, pellets!" in place of stronger language.
 * Paraphrased:

Yang: The Booby Trap factory, which is safe for you because you don't have bo-

Yin: Hold that insensitive remark!"

"Flash: Yep. Fastest man alive.
 * Dylan the rabbit from The Magic Roundabout was (at least in the UK Gag Dub) portrayed as an Erudite Stoner, and often said things that might have been about drugs. This gets a lot more blatant in The Movie.
 * Justice League is full of these.

Hawkgirl: Which might explain why you can't get a date.

Flash: Yeah... hey, what's THAT supposed to mean?"

"Hawkman: You always were good with that thing!"
 * Or Hawkman's remark after Hawkgirl attacks a villain with a whip.

"(While joking about Flash probably not having a chance with Fire): I hear she's, y'know... (Insert significant glance toward Fire, who is chatting with Ice.) ...Brazilian."
 * Interestingly, Hawkgirl seems to me involved in a lot of these:

"Amanda Waller: Bruce's DNA was easy enough to obtain. He left it all over town.
 * Another Hawkgirl example pops up when The Joker accuses her of "sublimating [her] passions with that big honkin' mace."
 * Possibly the most blatant example occurs in the episode where Flash and Luthor switch bodies. Tala, who had been trying to seduce Lex for a while, leads him (actually Flash) into the bedroom to "rest". Shortly after the door closes, we hear him happily chirp "Hey, that's not restful."
 * How about in the episode "Epilogue"? That was a pretty impressive one.

Terry McGinnis: [raises eyebrow]

Amanda Waller: Not remotely what I meant!"

"Princess Audrey of Kasnia: I'm a world class party girl. I intend to go out with a bang. Several, if it can be arranged."
 * A pretty infamous one:

"Professor Wakeman: You need new eyes like Oppenheimer needed gunpowder!"
 * And there's the episode where Flash and Wonder Woman rescue a magazine proprietor who looks a lot like Hugh Hefner (and letches on Diana). The exact nature of the magazines he publishes are unrevealed, but Wally insists he only buys them for the articles.
 * Katma Tui asking John Stewart if he still snores in his sleep...
 * Chip 'n Dale Rescue Rangers had a Cargo Cult episode with a tribe of kiwi birds. The tribe's chief, for no apparent reason whatsoever, spoke in nothing but Ed Sullivan mannerisms.
 * And don't forget the episode featuring a scientist named "Dr. Piltdown". Piltdown Man was, of course, one of the most well-known frauds in archaeological history.
 * The Lion King's Triumph of the Will-inspired imagery goes (one hopes) right over the kiddies' heads.
 * Of all the rides in Disneyland proper, "It's A Small World" is the safest for small children, and its Tastes Like Diabetes Ear Worm is nothing short of notorious. So it was a shoutout to plenty of long-suffering parents when Scar gave the song a great big Take That.
 * My Life as a Teenage Robot was full of various pop culture references, such as a group of villains named the Lonely Hearts Club Band... with a leader named Pepper. There was also this exchange, which goes past Parental Bonus into Viewers Are Geniuses territory:

"Arthur: This is all my fault!
 * One of the titular character's "sisters" sounded just like Marvin the Paranoid Android. One episode she asks to be given dreams featured the line "Pfft, what do androids dream of, electric sheep?"
 * Histeria!! sometimes had jokes that only the viewer's grandparents could get, such as a sketch of Thomas Jefferson writing the Declaration of Independence done as an episode of The Jack Benny Program.
 * Or saying of Greek Poet Sappho, "She didn't play well with boys."
 * Histeria was full of this stuff. Look at some of the songs. How many kids in their demographic would actually get songs based on "Ghostbusters" or "Theme from Shaft"?
 * Hell, the show had Grandparental Bonuses. Jack Benny as Thomas Jefferson, Bob Hope as George Washington, Frank Sinatra as Caesar.
 * In the Avatar: The Last Airbender episode "The Cave of Two Lovers," the Gaang meets up with some extraordinarily 60s Hippie-ish, guitar playing nomads with vocal characteristics of The Stoner. When the cave group is traveling, their leader shouts "The tunnels, they are a-changing!" How many kids in the target demographic got that reference?
 * Even better, the leader of the nomads was named Chong.
 * What about Sokka waiting for Suki in a tent filled with flowers and candles, and not wearing any pants?
 * Also, in the episode "Sokka's Master," Piandao is voiced by Robert Patrick, who plays the T-1000. A Shout-Out to sword arms is involved.
 * When choosing their vacation spots, Sokka tells Toph she hasn't worked with them long enough to choose her vacation.
 * All of the violence is normally something a child would not understand.
 * Danny Phantom has its moments - Desiree and Vlad are both walking Parent Service, specifically. The eighties and college references help as well. It also has it's share of Double Entendre.
 * Face it Nickelodeon loves these to death. Seriously.
 * George Shrinks has the titular character, at one point, tell a bee to go pollinate itself.
 * One episode of Cow and Chicken had a gang of butch female bikers (Cow even calls one of them "sir") who crashed into people's homes and literally munched on their carpets.
 * In the first episode of Doug, Doug is tricked by Roger into searching for fictional creatures called "neematoads". While searching in the marshland, he spots Roger laughing at him and realized he's been fooled. Doug's dog who became covered in mud approached Roger, convincing Roger that it was a neematoad. The episode ends with Roger searching in the marshland for neematoads. There is no such thing as neematoads, though there is a such thing as nematodes. And considering that both Doug and Roger were barefoot while searching, they definitely found some...
 * Much of Fillmore parodies 70s cop shows specifically, and relies heavily on What Do You Mean It's Not Awesome?.
 * And how many kids were they expecting to get all of The Silence of the Lambs references in the episode "To Mar a Stall"?
 * One episode of Arthur featured the characters all writing stories for a TV show's story contest (the stories themselves written by kids, or so it says at the end), which were then played out using the Arthur characters in the animation style of other cartoons... including South Park, Beavis and Butthead, and Dr. Katz, Professional Therapist.
 * In the episode when Buster is diagnosed with asthma, Arthur accidentally induces an asthma attack when he's reading an old, dusty joke book with Buster. The following exchange with his father ensues:

Mr. Read: How could it be your fault?

Arthur: It's because I showed him those dirty books! That's what made him sick. I just know it!

(Confused look on Mr. Read's face)"

"J. Gander Hooter: But FOWL High Command must surely realize that one hundred trillion dollars is difficult to come by!
 * In one Arthur episode there was a band called "Binky" that looked and sounded suspiciously like ABBA. They had the same amount of popularity and were even from Europe.
 * In another episode, when The Brain and Sue Ellen are going to do a science project, Brain imagines himself explaining that he managed to resurrect a dinosaur at a science seminar. Said dinosaur turns out to be a Tyrannosaurus Rex, and the audience is understandably scared. Brain then tells them to stay a bit. The Tyrannosaur is then given a microphone and then recites a Groucho Marx joke (more specifically, its the one where Groucho Marx explains that one day, he found an Elephant in his pajamas, and that he'll never know how it got in there).
 * Derek Blunt, in the Darkwing Duck episode "In Like Blunt" is a parody of Derek Flint (who is, in turn, a parody of James Bond). The episode title is a parody of the second Flint film In Like Flint (which is, in turn, a parody of the phrase "In Like Flynn"). It's unlikely kids would get any of these references except Bond.
 * Darkwing did this all the time. Take the episode "Twin Beaks": the alien cows claim to be from the planet Larson, on "The far side of the galaxy." The Far Side was created by Gary Larson, who made more comedic use of milk cows than Earthworm Jim.
 * "Trading Faces" gives us this little gem.

Steelbeak: Hey, read my beak; tell them to raise some taxes. Eh heh heh, like they need an excuse, right?"

"Bloo: It's a hundred and six blocks to Mac. I've got a full bladder, half an idea where I'm going, it's Tuesday and I'm wearing sunglasses.
 * Foster's Home for Imaginary Friends. For example...
 * In one episodes, Mac was frustrated because Bloo left him (clearly behaving more like a husband whose wife just left him than a little boy whose BFF just left him). To make it even better, Mac goes to an ice cream parlor right afterward.... and everybody who watches the show knows that he reacts to sugar like others react to drugs. The following scene looks... ripped out of a relationship-drama movie.
 * In Partying is Such a Sweet Soiree, Bloo tells Mac what they got for their party: "...and on the 6th floor, Ring around the Rosey, If you know what I mean..." Mac answers: "Not really." Bloo: "Yeah, me neither." And just a few minutes later, Mac gets into a pretty extreme form of the Mushroom Samba. Sugar seems to contain ecstasy in the FHFIF-universe, at least for Mac. "High" doesn't even come close to describe sweet little Mac's behaviour for the rest of the episode.
 * In the episode Store Wars, the group passes by the window display of a store for women's underwear. Bloo walks right past it, but 8 year old Mac takes a glimpse while smiling in a pretty strange way. Adult woman Frankie and female imaginary friend Coco look at it interested and coward Eduardo covers his eyes in horror.
 * That show had a Blues Brothers reference of all things. And not just any Blues Brothers reference, they almost quoted verbatim the most famous line of the movie:

Frankie: Hit it."

"Who's that tap-tap-tapping on my window? Is that a raven? Stupid ravens..."
 * A random character with Morrisey-esque hair talked entirely in altered Smith's lyrics.
 * On a similar note, in the episode "Nightmare on Wilson Way", after Eduardo becomes a zombie, Bloo mutters "Well, Ed is dead." "Ed is Dead" is the name of a Pixies song.
 * They also parodied the Death Star trench run. No, not Luke's, Red Leader's. And in an episode that Blu gets fantastically rich, he sails around inside the house on a tiny steamboat. It's name: The Bloosatania. And then there was Arthur Dent trying to Hitchhike to Magrathea...
 * As well as two nerds named Douglas and Adam, one of which wears white shirt with a large '42' printed on it.
 * Mac waking up next to Cheese and trying to 'explain' to Bloo.
 * Re Boot is full of these, with constant references to pop culture (both American and British) and computer terms. Whole episodes would do this, notably the homage to The Prisoner, "Number 7". To the hordes of little kids who didn't know The Prisoner existed, the plot was a terrifying mindfuck full of creepiness. The end of Series 2 even had references to the Blitz of London; as a result of a war in the sky, the Binomes shelter in Tube stations, and Binomes resembling the Women's Auxillary Air Force are working as spotters in the War Room.
 * Don't forget the cabin from Evil Dead!
 * Also don't forget the season 3 recap at the end, performed by the Mainframe Players in the style of Modern Major General.
 * There was also the season 2 episode Bad Bob, to say nothing of season 3's masterful lampoon of Star Trek: The Original Series
 * Although Wonder Pets is usually rather light on Parental Bonus, the episode "The Wonder Pets Save the Beetles" is filled with non-stop references to a certain rock band...
 * The Beetles were voiced by two of the performers of Broadway's "Beatlemania."
 * To say nothing of "The Wonder Pets save the Fiddler Crab on the roof."
 * And "The Wonder Pets Save the Rat Pack. Not only are the guest characters based on Sinatra, Davis, and Martin (with dead-on voice acting), but Elvis Presley and Raoul Duke can be spotted in a crowd.
 * The more recent episodes of Wonder Pets are chock full of Parental Bonus - Save the Vixen, a noir style episode guest starring Lauren Bacall, and full of nods to the films, Save the Skunk Rocker, full of references to classic punk and Save the Rock Lobster, a B52s inspired episode, in particular.
 * Donkey Kong Country had a scene where Diddy utters the phrase "the only thing worse than a bruised banana is a bruised butt." Yeah.
 * The Playhouse Disney show Special Agent Oso has episode titles like "Gold Flower" and "A View To A Kitten".
 * The Marvelous Misadventures of Flapjack in the episode "Whale Times." Bubbie meets a whale names Harvey, and they like each other. Bubbie isn't that kind of whale though. Also with that comes an innocent-Flapjack comment after they realize Harvey kidnaps people from other giant creatures, "Harvey sure does get around."
 * Ruby Gloom makes a rather obscure Beatles reference in the episode "Beat Goes On", when Frank cries out "I got blisters on my fingers!". Frank is quoting Ringo Starr, who says exactly the same thing (in the same tone of voice) at the end of the song "Helter Skelter".
 * Codename: Kids Next Door has entire episodes based on parental bonuses. Apart from parodies of such non-kiddie friendly films as Terminator (Operation FUTURE), Soylent Green (Operation HOME), Minority Report (Operation CRIME), The Empire Strikes Back (Operation SNOWING), and the Alien franchise (Operation LICE), there are e.g. Operation POINT where the kids try to find out what teenage couples do to "become adults" up at "The Point" on Saturday night  and Operation SUPPORT where Nigel and Hoagie decide that bras must be secret weapons ("Battle Ready Armor!!") and sneak into Abby's sister's bedroom to steal some for themselves..
 * Then there's an episode based on Isaac Asimov's book Fantastic Voyage, in which 4 ate a brussels sprout and the rest of the team got shrunk to retrieve it (Operation SPROUT).
 * And then there's Operation RECRUIT, which is more or less a direct parody of The Matrix
 * And Operation ARCHIVE, which is a direct parody of the Animatrix segment "The Second Renaissance".
 * Numbuh One dresses up as a Borg in the Halloween episode and even says "You will be assimilated joinified."
 * Actually, Numbuh One himself is kind of a parody of Captain Picard. I mean, bald Brit who's in charge and says "Numbuh One" a lot...who does that remind you of?
 * And there's Operation DUCKY that was a parody of Moby Dick in a ginormous bathtub with a giant rubber ducky and a Captain Ahab Expy who talked like William Shatner.
 * Operation COUCH- most of it, especially Emperor Dave.
 * Thomas the Tank Engine has an episode titled "Escape", where Oliver is saved from scrap. The music that plays while he's being spirited away from the diesel area is clearly based on the famous tune from The Great Escape.
 * As quoted above, Phineas and Ferb. Very little of what makes the show good can be properly understood by the target demographic.
 * The Phineas and Ferb special "The Summer Belongs To You" had the gang stop in Paris. While in it, Phineas gawks at the Moulin Rouge. What is the Moulin Rouge?
 * Also, in "Phineas and Ferb's Quantum Boogaloo" when Candace's time travel causes Doofenshmirtz to take over the world, he sings a song called, "It's a Charmed Life". One of the lyrics is "Everyone else is the proletariat and baby I'm the bourgeoisie! Look it up Joe!" Most kids, in fact quite a few adults, do not know those words.
 * In one episode, when Perry tapped on Doofensmirtz's window and then disappeared offscreen, Doofenshmirtz opened up the window and made a rather fantastic literary reference...

"An adult: Aren't you a little young to know about all these old detective shows?
 * Not to mention that the entire "Harbor Day" episode was a giant parody of a certain story concerning a crazy captain and a whale...
 * From the episode "Finding Mary MacGuffin":

Phineas: Yes. Yes we...


 * puts on sunglasses*

Phineas: are.

YEAHHHHHH!!!!!"


 * The Adventures of Jimmy Neutron had a good number, being another Nick show. Anyone recall that episode where Cindy and her friends were having a garage sale, and Sheen finds a bra and proclaims it to be an Ultra Lord Double Barrel Slingshot?
 * "I don't know, Sheen, if that's the case, then my mom has a lot of Ultra Lord Double Barrel Slingshots..."
 * From The Magic School Bus:
 * At one point, the bus turns into the Enterprise.
 * Not to mention the Friz herself. As many a disgruntled cosplayer has noted, Ms Frizzle is stacked.
 * In the episode where they go to space, they are going past Uranus. Arnold jumps into his cousin's lap, to which she says, "Uranus Is Showing doesn't do a thing for me, so please get off!" Arnold replies, "Sorry, Janet, but I have to stay on top of the situation."
 * In "Gets Ready, Set, Dough", while the class is stuck in an oven, Phoebe says, "At my old school, we never got baked."
 * When Ms. Frizzle is put on trial for taking Keesha's cucumber ("In A Pickle"), her prisoner number is 24601.
 * On an episode of Tiny Toon Adventures, Buster, Babs, Plucky, and Hamton go on a treasure hunt. They find it buried under trees shaped like an X, and later, as they're fighting over the treasure, Plucky gets caught in a tree. As his treasure pours out of his bag into Hamton's, Hamton notes "The trickle-down theory", which would require quite a bit of knowledge of economics.
 * Wallace and Gromit's Gromit has been seen reading the following books: "Electronics for Dogs," "Pluto's Republic," and (while in prison) "Crime and Punishment" by Fido Dogstoyevski. Gromit was also enrolled in Dogwarts University.
 * There's also the scene in The Curse Of The Were Rabbit where Wallace's contraptions go wrong and he ends up naked in his kitchen except for a box around his waist. The box reads, "Caution: may contain nuts."
 * Not really a funny one, but in one episode of Batman Beyond, Barbara Gordon comments that people finding out about her past may jeopardize her husband's run for re-election. Younger children would probably not understand that (why would anyone hate Batgirl?)
 * In one episode of Coconut Fred's Fruit Salad Island, there were a number of jokes inserted into the episode that were throwbacks to old video games. The only one the children got was "MARIO!" and the only one the adults cared about was "FINAL FANTASY VII!" Sucks to be you, Link and Kirby.
 * Atomic Betty: On Season 2, Episode 17 "Extreme Makeover" (featuring the villain Bombshelle). Betty's mom is trying her old dancing clothes and Noah walks in. She asks him to watch her performance for a while and dances. After she finishes, there's a shot with a dumbfounded Noah at the door, looking at Betty's mom raised leg on the foreground. Noah, being a little kid, has a different reaction (he almost throws up - of course, Betty's mom choice of bright pink gym clothes might have something to do with it).
 * The sketch show MAD loves this trope, having references to many things the target audience probably wouldn't know, such as CSI or The Bourne Identity, the references are usually mixed with something the target audience has seen, such as iCarly and Bob the Builder
 * Batman the Brave And The Bold has a song from the trio of Black Canary, Huntress, and Catwoman that's not so much Parental Bonus as "Get the kids out of the room now. The song starts by listing the sexual issues of the male heroes through very poorly disguised lyrics: Green Lantern's "ring" is small but pretty strong; Blue Beetle is cute but is an inexperienced virgin; The Flash, of course, is "sometimes way too fast"; Green Arrow is a switch-hitter; Aquaman's "little fish" is unimpressive; and Plastic Man has, obviously, all sorts of interesting possibilities. And then to wind it up, they're inviting Batman to join them for a foursome.
 * My Little Pony Friendship Is Magic is packed with these. Some examples involve Benny Hill homages, obscure and cult movie shout outs, Viagra-like potions for a rooster who can't "sing" anymore, and of course, the famous The Big Lebowski ponies from the pony bowling alley. See trope page for examples.
