Brick Joke/Western Animation

"Wonder Woman (surprised at the serious tone in Deadman's voice): That's a pretty thick shake."
 * Several Road Runner/Coyote cartoons employed this joke. One of Wile E. Coyote's failed devices from the beginning of the cartoon does him in at the end.
 * Coyote installs a large metal plate underneath the road that springs up on command, intending for Road Runner to smash into it. It fails as usual and Coyote tries to figure out what went wrong, the audience expecting it to spring up and launch him into the air or something similar, only nothing happens. Later in the episode, Coyote has employed one of his numerous methods for matching Road Runner's speed and proceeds to chase him, until...
 * In another case, Coyote tries to blow Road Runner up using a glass of water on a box marked "free drink" which when taken would light a match setting off the Kablooie! Road Runner ignores the water, he informs Coyote that he can't read, and doesn't drink. Several gags later, Coyote climbs out of an Efficient Displacement hole in the ground only to crawl, tired and thirsty to the same box. After grabbing the water, there's just enough time for an Oh Crap moment before the inevitable non-lethal Earthshattering Kaboom.
 * In one episode of Kevin Spencer, Kevin and his dad make a scarescrow and pass it off as a disabled person so they could get into a hockey game. This thing appears in one scene at the beginning, and once at the end, where a news reporter thinks it's a lost child.
 * Popeye occasionally exhibits this trope. In one episode, Bluto is a Carnival Balloon jumper (he jumps from a hot air balloon using a parachute). When Bluto sees Olive Oyl, he ties a balloon to his announcer, who floats away. At the end of the episode, Popeye and Olive are floating down using an umbrella, and the announcer floats by, still yelling about Bluto's act.
 * SpongeBob SquarePants: SpongeBob is training Gary for a snail race, and tells him, "I called you a lady to humiliate and demean you." Cut to Sandy, who says, "I don't know why, but I think I'll kick SpongeBob's butt tomorrow." Then, at the end of the episode when everyone has forgotten about it, Sandy shows up out of nowhere, kicks SpongeBob's butt and yells, "That's for yesterday, Squarepants!"
 * In "F.U.N." SpongeBob seeks Plankton's friendship, in the hopes that he'll be a nicer person for it. He knocks on Plankton's door, and SpongeBob tells him he can help him. Plankton responds, "You know how to induce thermonuclear fusion?" SpongeBob begins, "No, but I like to go jelly-" before Plankton slams the door in his face. Plankton launches into a rant about how stupid SpongeBob is, before having a conversation with his computer, who convinces him to use SpongeBob's friendship as a means of stealing a Krabby Patty. Plankton agrees, and goes to fetch SpongeBob, but when he opens the front door, SpongeBob is standing there, and says, "-fishing with my friends in Jellyfish Fields."
 * In the episode "The Two Faces of Squidward" some random fish gains the ability to fly. Because of an untied shoelace his shoe falls off. The episode continues and everyone forgets about it. At the very end, the shoe crashes through the ceiling of the Krusty Krab and hits Spongebob. A day later.
 * "Toy Tinkers". Donald Duck and Chip and Dale are fighting over candy and sweets in a Christmas setting and are currently engaged in trench-warfare with Christmas balls and toy weapons. Dale plants a phone on Donald's side and, when Donald answers, Chip fires a toy cannon at him through the phone. Donald tries to reverse the trick eventually by stuffing a firecracker/"stick of boom" into his end, dialing them, and lighting it when they answer. The audience can see the natural conclusion coming from a mile away: it's going to blow up in his face. But the fuse snuffs out at the receiver, and Donald hangs up in anger that nothing happened. He's about to resume fighting when he has to answer the ringing phone. BOOM.
 * The 1953 Disney short Rugged Bear features Humphrey Bear seeking a safe place to hide during hunting season. He ends up in the cabin of Donald Duck, and notices a bear skin rug on the floor. He hides it in a chest and the remainder of the cartoon is his attempt to pass himself off as the rug while enduring endless indignities at the hands of Donald. He is used as a match striker, bottle opener, nutcracker, and blanket. He gets set on fire, beaten out, put through a washing machine, brushed, raked and finally mowed back into shape, and then rolled up to be slept in. After hunting season has passed Donald departs and Humphrey can finally stop pretending to be a rug. Whereupon the original "rug" (whom the entire audience has long since forgotten about) reveals itself to also have been a live bear, exits the chest, and thanks Humphrey for taking his place.
 * In the second Mighty Mouse series, there is a battle between the Mad Cow and The Legion of Super Marsupials (and Mighty Mouse). In the fight at the beginning of the episode, The Sloth winds up his "Super Slow-Mo Punch" - promptly freezing. The episode continues, with Sloth standing still in the background of scenes in the HQ. At the very end, as Mad Cow appears to triumph, the punch connects, defeating him.
 * In the first episode of Megas XLR, Coop and the eponymous mecha stare down a group of alien mechs, and Coop presses the button... firing a missile straight up into the air that connects with a PopTV broadcast satellite. Later, when the army re-forms into the UMD, the satellite crashes down and destroys the ridiculously oversized mecha. This is just one of many, as Brick Jokes happen so often in Megas XLR to qualify as Once an Episode.
 * Winx Club: An episode ends with Layla sadly reporting that her parents have set up a marriage for her. Several intervening episodes and plotlines later, Layla brings up this long-since-forgotten-by-the-viewers issue while supporting her friend's choice to break up with her boyfriend. And cue subplot.
 * To add to the brickiness of this, the original US airing saw a lengthy hiatus. Result: Layla first mentions the Arranged Marriage in March '07, and doesn't mention it again until July.
 * Avatar: The Last Airbender: The war meeting in "Nightmares and Daydreams" that everybody complained about not getting to see. It was eventually shown in a Flash Back in the series' finale -- and it's revealed they had a very good reason not to show it then.
 * Also Jet could count as one. I for one forgot all about him after his single episode in the first season
 * A brilliant one, set up in the seventh episode of season 1 (The Spirit World): Sokka is kidnapped by the spirit Haibei, and released 24 hours later. When asked how he was feeling, he said, "Like I seriously need to use the bathroom." Then, in season 3, episode 6 (The Avatar and the Firelord, thirty-nine episodes later), Aang mounts Roku's dragon in the spirit world, while acting out the same movements in the physical world. Katara, who cannot see the spirits, asks, "Do they have bathrooms in the spirit world?" to which Sokka replies, "As a matter of fact, they do not."
 * One in the Book Two episode "Avatar Day" has Sokka making an offhand remark about how good the deep-fried festival food that the Adventure Town of the day makes during Avatar Day. At the end of the episode, the town has changed the festival food to unfried dough in the shape of Aang, which previously required deep frying in oil.
 * "Boomerang! You do always come back!"
 * Futurama, "Xmas Story": Fry buys Leela a parrot, but it escapes. After Fry falls trying to get it and Leela saves him, the parrot is forgotten. Later, when Robot Santa fires a missile on them, who should appear but the parrot, unwittingly saving them by getting in the way of the missile.
 * And then, after you've once again forgotten about the parrot, Bender shows up with X-mas dinner, which turns out to be the corpse of the parrot, which he found lying in the street. Double Brick Joke!
 * Also in "Teenage Mutant Leela's Hurdles", they start off by chasing the Professor's escaped monster, which is forgotten about. At the end of the episode, the monster turns out to have been hiding in the Planet Express ship all the time, and saves the Professor's life, thus earning his freedom.
 * Futurama uses this a lot. In "How Hermes Requisitioned His Groove Back", after being demoted, Hermes almost commits suicide ends up spending a paid vacation in a forced labor spa. While there, there's a brief scene where his bureaucratic instincts cause him to double the workload of an unnamed Australian man who's also working as a laborer. His efficiency in this task encourages him to pursue his career as a bureaucrat again. The viewer thinks it's just a gag to move the plot along, but when Hermes shows up two scenes later, his wife remarks that he got the labour camp running so well that, "All the physical labor is now done by a single Australian man."
 * In this same episode when Hermes is threatening to commit suicide, Professor Farnsworth urges him not to jump, instead asking for him to use a method that "wouldn't damage that healthy liver". Later, when Hermes shows up to save the day, Farnsworth yells at him to "quit hogging that liver".
 * In "Put Your Head On My Shoulder", the episode begins with Bender having an issue with his butt such that pressure could make it explode. He gets shock absorbers installed, but asks for them removed because of the appearance. The episode then goes into a Valentine's Day plot, in which Fry's head is severed from his body and attached to Amy's. When, at last, his head is re-attached to his body, a loose nerve causes him to kick when touched - and he happens to kick Bender's butt.
 * In "Fear of a Bot Planet" Bender is sent on a delivery mission to a planet occupied by human-hating robots, but gets captured due to him working with humans. Fry and Leela disguise themselves as robots to rescue him, but are found out and arrested. They then meet the Robot Elders, who talk about the planet's lug-nut shortage as the reason humans are scapegoated as evil. They escape with Bender, but are followed by a mob of robots, so Bender throws the package he was meant to deliver, which just so happens to be filled with lug-nuts.
 * In "Three Hundred Big Boys", Bender spends his $300 tax refund on a burglary kit so he can steal a $10,000 cigar. At the very end, after the cigar burns down an art exhibit, Bender is apprehended by the recurring buddy cop duo and joyously shouts, "All right! Closure!"
 * Also during that Episode, Fry is determined to use the money to drink 100 cups of coffee. By the time he does, he gains superhuman speed and uses that to save everyone from a burning building.
 * In "How Hermes Requisitioned his groove back", while waiting in line at the Central Bureaucracy, they meet a man who is waiting for his birth certificate. Four seasons later, in "Lethal Inspection", they visit Central Bureaucracy again and the old man finally reaches the window, he's told he was waiting in the wrong line and dies.
 * In the beginning of "War is the H-Word," Fry and Bender attempt to buy a pack of Big Pink ham-flavored chewing gum with a military discount, only to discover that the discount only applies to people in the military. Later, at the end of the episode, Henry Kissinger's head remarks that Fry's breath is "as fresh as a summer ham."
 * In the episode "Amazon Women in the Mood" Zapp gives Kif a book of (terrible) pick-up lines to use on his half date with Amy. One of the lines Kif nervously blurts out is "I find the most erotic part of a woman is the boobies", later, after Leela, Amy, Zapp and Kif crash land on planet Amazonia, Zapp gives away their position to the massive Amazonian women by using the pick-up line "I find the most erotic part of a woman is the..." before getting cut off.
 * In the Tex Avery short Rock-a-Bye Bear, a guard dog for a hibernating bear has to stay quiet while another dog tries to get him fired by making noise. Early on, the first dog gets rid of a pin-up poster (to avoid the temptation of blowing a Wolf Whistle) by folding it into a paper airplane and throwing it out the window. At the end of the cartoon, the airplane lands into the hands of the second dog after flying for who knows how many kilometers. The dog unfolds it, whistles, and sure enough, the bear wakes up to beat the tar out of him.
 * In the Lucky Luke animated movie Tous ?'Ouest, Luke fires at the Daltons during a pursuit in a mine. The bullet misses and starts ricocheting the walls before disappearing in the distance, to Joe Dalton's mocking remarks. Way, way later, Joe holds a girl hostage and forces Luke to drop his guns, which he does. Luke then points his fingers at Joe and imitates the sound of a gun firing. And suddenly the earlier bullet ricochets out of the mine and neatly disassembles Joe's gun...
 * Pelswick: There is a school science fair going on. One of the exhibits is a diagram of intelligence from the school principal (dead last) to a chicken. At the end of the episode, we see the principal in bed, when he suddenly pops up, exclaiming "Hey! I'm smarter than a chicken!!!"
 * Family Guy has many:
 * In "Believe It or Not, Joe's Walking on Air", Cleveland criticises the Scrubs hypothetical spots for being stupid and irrelevant, and a nonsensical cutaway of Hitler juggling fish while unicycling pops up. Half an episode later, another cutaway is set up where Peter says that taking care of Joe is "the right thing to do, just like taking out Hitler", and flips back to the earlier scene... then Peter comes out and punches Hitler off the unicycle, adding "See? We had a plan for that one all along."
 * "Road to Germany" had a bit where Stewie plays with a European toy that says animal onomatopoeia in different languages. Later, he hears a cow say one of those and figures out he's in Europe.
 * In "Petarded", there's a gag about a Discovery Channel documentary about fire engines hunting gazelles in the Savannah. It's good for a laugh and then forgotten, until the end of the episode, where, after the plot, a fire engine attacks the house.
 * In "420", they cut away to Peter taking great pleasure in spotting the Title Drop in various movies and TV shows. Later on in the main plot, Brian is arrested for possession of pot and the cop says "I don't want drugs in my town! I'm a family guy!" Peter goes wild!
 * Also in "420", Peter and the gang kill Quagmire's cat. Peter then wraps the body in his coat and drives off to bury it when he's stopped by a police officer, who notes that Peter is covered with blood and has a suspicious package in the back seat. The cat's death is quickly forgotten when the cop arrests Brian for possession of marijuana, then shifts to the plot of Brian starting his petition to legalize it. We don't hear about the "cat killing" plot again until the end of the episode when Quagmire asks Peter where it is and Peter nonchalantly tells him he killed it.
 * In "Tales of a Third Grade Nothing", Peter accidentally blows up a children's hospital in order to remove a competitor's advertisement billboard. At the end of the episode, he is found guilty and serves time in jail.
 * In the same episode when Angela mentions she recommended Peter for a promotion, Peter says that he had eaten a fortune cookie which said that an obvious lesbian would bring great news. He also mentions it said a grand piano would fall on him and then looks up to make sure he is safe. He then leaves the room as nothing falls on him, but one does a few minutes later.
 * In "No Chris Left Behind" Peter interrupts a serious conversation with Lois to embark on a destructive, citywide fistfight with the Giant Chicken. Eventually he makes his way back to the house and finishes the sentence he started several hours and eight billion punching sound effects ago.
 * The giant chicken itself can count. How many people thought we'd never hear from it again after the first fight in Season One.
 * Let's not forget The Surfin' Bird song in "I Dream of Jesus". The entire first act kept Peter singing this song. After the records were destroyed, the plot with Jesus began. At the end of the episode, Peter is reminded of it and starts singing again.
 * At the beginning of the episode "Family Gay", Peter buys a horse that eventually dies, so he flings its body into Mort's pharmacy. At the end, Mort throws the corpse through the window of the Griffins' house, shouting, "Take back your fucking horse!"
 * Almost a literal brick joke, except the brick is a dead retarded horse.
 * In "Dog Gone," a drunken Brian responds to the father from Family Circus attempting to give him advice by telling him to go "f*** your wife in the face." The father pleasantly agrees to do so. A later scene shows Peter reading the newspaper and saying, "Well, that was a very shocking Family Circus."
 * A chain brick in "Blind Ambition". First, Peter found Judd Hirsch in a bowling pin making a nuclear weapon. Later, Stewie crashed into a tree and found the Keebler Elves waiting for Judd Hirsch's weapon so they could attack the Rice Krispies guys. And finally, when Peter's at the bar, he sees Crackle and Pop mourning the loss of Snap in the attack.
 * In "Stewie Kills Lois" Meg takes a pack of hot dogs to her room and says she is going to pretend they're the New York Knicks. Peter later says he has to go buy hotdogs because they keep running out for some reason.
 * In the 1997 Looney Tunes short "Father of the Bird", Sylvester . He forgets about it right after that, and suffers through a couple more gags before.
 * Also, in "Blooper Bunny", during the Hilarious Outtakes portion of the cartoon, Bugs stops everything in the middle of the second take to warn about a loose floor board. Later on, Elmer Fudd makes an attempt on Bugs's life, causing Daffy to go on a rant, and just as he finishes, he steps on the same floor board and gets smacked in the face.
 * Early in the South Park episode "About Last Night...", Cartman tries to sell (presumably stolen) TVs to Stan and Kyle. At the end of the episode, Randy finds his TV missing.
 * In an earlier episode, "How to Eat With Your Butt", a news report in the background mentions a man killing people with a motorcycle. In the last few minutes, said motorcyclist comes through and kills Kenny.
 * In "Imaginationland," a bunch of cute but psychotic woodland creatures kidnap Strawberry Shortcake and gouge out her eye. They decide to kill her by infecting themselves with AIDS and pissing into her open socket. Later, when Stan is exploring the place, he mentions off-camera that he found Strawberry Shortcake dead with some pee in her eye.
 * And let's not forget Lemmiwinks!
 * Early example: "The Succubus". There is a Running Gag of Chef's parents talking about various encounters with the Loch Ness Monster, with the monster wanting $3.50. Then, at the end of the episode, the eye doctor casually asks Cartman, "Say, you wouldn't happen to have $3.50, would you?"
 * Used a lot on The Simpsons:
 * In "Sideshow Bob Roberts", Burch Barlow announces on the radio one of the few things the town of Springfield is never going to get rid of is the bats in the public library, a crazy woman's compost pile, and the mayor Joe Quimby. Later when Bart and Lisa go to the library, bats fly out and swarm them. This brick joke has even carried onto many other episodes that feature the library.
 * "A Tale of Two Springfields" starts off with Homer trying to get a badger out of Santa's Little Helper's doghouse, before being distracted by the discovery that Springfield now has two area codes, which eventually leads to the main plot of the town being divided in two and the fight over which side will get to host a concert by The Who. (The badger even looks through the window, only for Homer to essentially tell it its role in the story is over.) Once the town is reunited, we cut to the hills above it, where the badger is leading its fellows to attack.
 * If you watch the American syndicated version, it quickly becomes a What Happened to the Mouse? moment, as all scenes with the badgers trying to incorporate themselves in the story are cut, along with the ending.
 * On the Treehouse of Horror story "B.I.: Bartifical Intelligence," Bart jumps out of Patty and Selma's window, aiming for the pool. He yells "COWA-" and is cut short when he hits the ground, ending up in a coma. Later, he wakes up, yelling "-BUNGA!"
 * In "The Front," the opening scene features Homer getting a plunger stuck to his head. The episode moves on to feature a B-plot of Homer being revealed to have never graduated high school and studying to finally get his degree. The final scene features him getting it and declaring that at his next high school reunion he'll have nothing to be ashamed of. Flash forward to the next one, where he's somehow arrived at the reunion with a plunger on his head without either himself or Marge noticing.
 * In the episode "This Little Wiggy" early on after being set up for a play date with Bart Ralph shows him his backyard and he tells him of his friend the leprechaun who tells him to burn things; Bart replies sarcastically, "Right." At the end of the episode when the family thanks Ralph for organizing the plan to save Mayor Quimby from being electrocuted, the leprechaun appears on his shoulder and tells him "You did a fine job, laddy. Now you know what you must do. Burn the house down! Burn them all!" Ralph smiles.
 * One episode begins with Principal Skinner locking Bart and the bullies in a military-grade shelter underneath the school before Superintendent Chalmers's school inspection. Bart, who manages to crawl out through a vent, is supposed to free them, but . The plot takes off from there, days or weeks go by (with the main focus switching from Bart trying to get an education now that and Lisa protesting against Whacking Day), and only at the very end of the episode does Skinner realize, to his horror, that the bullies are still in the basement shelter and.
 * In another Treehouse of Horror, in a parody of The Shining, towards the beginning of the trip to the hotel there's a throwaway gag where Lisa points out that they left Grandpa at the gas station, and nobody cares and they just keep driving. After Homer goes literally Ax Crazy, he chops down a door, only to see Grandpa, who has just arrived.
 * In "When You Dish Upon A Star", Homer meets Alec Baldwin, Kim Basinger, and Ron Howard. He shows them a movie script he has for them about a killer robot driving instructor who goes back in time for some reason, a buddy picture with a talking pie. They pass on it. At the end of the episode, Ron tells a film executive about an idea for a movie where a father has to choose which one of his children will live and which one will die. The executive decides to pass and then Ron tells him his other idea is about a killer robot driving instructor who goes back in time for some reason and has to make the exact same decision. The executive isn't sold on the idea until Ron adds that the robot's best friend is a talking pie.
 * On the season nine episode, "Realty Bites" (the episode where Marge becomes a real estate agent and Homer buys Snake's car at auction), there's the scene where Snake uses piano wire to decapitate Homer as he's driving. Homer narrowly misses it when he finds a gumball under the seat, but Milhouse's dad (who's driving in a similar red convertible) drives by, complaining about his sandwich not being cut, then ends up with his arm sliced off (originally, his sandwich was going to be cut, but the writers thought it was too predictable). When Marge loses her job as a real estate agent and goes to the unemployment office, Milhouse's dad is shown in line (along with Jimbo Jones, Lurleen Lumpkin [the country singer from "Colonel Homer" who fell into drug problems as seen in "Marge vs. The Monorail"], Mr. Burns's son from "Burns, Baby Burns," and the hippie in the fishing hat who got fired from his job as an "Itchy and Scratchy Show" writer on "The Itchy and Scratchy and Poochie Show" for speaking out creating Poochie) with his arm bandaged and in a sling.
 * Deep Space Homer has an opening where Homer loses an employee of the week award to an Inanimate Carbon Rod. After the entire episode goes past, with Homer going into space, and then saving his, Buzz Aldrin and the 3rd crewmember's life by jamming a 'bar' into a broken hatch they come back to earth. When they open the hatch, a gaggle of reporters ask them how they survived. Buzz Aldrin then says Homer is the hero because he jammed the bar into the hatch. Homer pulls out the bar, lifts it into the air in triumph. A reporter asks "What is that?" and another exclaims "It's an inanimate carbon rod!" The rod is then featured on the cover of Time Magazine.
 * "Itchy And Scratchy Land" has a scene where Homer and Marge go to T.G.I. McScratchy's and talk to a waiter who is getting tired of their constant New Years' celebration. Later, Marge and Lisa pass a control booth, where one viewer notices "another jumper on the roof of T.G.I. McScratchy's".
 * One nickname in the credits "Treehouse of Horror XIV" is "The Repubican Party". One nickname in "Treehouse of Horror XV" is "No, Seriously, The Republican Party".
 * In the "It's a Good Life" parody in "Treehouse of Horror II" America becomes Bonerland to correspond with Bart's history test. Marge later takes Bart to Dr. Marvin Monroe who is a member of the Bonerland Medical Association.
 * In an early episode of Rocko's Modern Life, "Carnival Knowledge", Rocko and Heffer go to a carnival. One of the activities involves launching a frog into the air and having it land on a lilypad. After several attempts Rocko finally launches one in the air and it doesn't come down...until the very end of the episode, where the frog finally lands on a lilypad, meaning Rocko won the game.
 * In "Teed Off", Heffer is working as a groundskeeper at a golf course, and is seen using his tractor to make crop circles. At the end of the episode, it shows a pair of aliens visiting the course at night, looking at Heffer's crop circle, and one of the aliens says "Who keeps writing this stuff?!"
 * The Fairly Odd Parents uses this trope often. One prominent example can be found in the season one episode "Father Time": Timmy wishes for heat vision at the start of the episode in what appears to be a gag demonstrating Timmy's stupidity; the wish is promptly forgotten once the main plot kicks in. Towards the end of the episode, Timmy remembers the heat vision and uses it to set things right.
 * Another example in the same episode has present day Cosmo and Wanda talking 70's Bill Gates out of naming his idea of linking every computer in the world "The Internet", getting him to call it "The Timmy" instead. At the end of the episode, Timmy's Dad mentions buying a new trophy from the Timmy, with Mom referring to Timmy as Internet.
 * The heat vision comes back during "Escape from Unwish Island" in season five, when Timmy rummages through a closet of old wishes for items and remembers that he still has the ability. Whereupon they all explode.
 * In fact, Timmy never unwished Heat Vision, and he will periodically remember this whenever he needs it.
 * In the beginning of one episode of The Inspector (part of the Pink Panther series), the Inspector gets Sgt. Deux-Deux to loan him money in order to capture a notorious pick-pocket, despite Deux-Deux warning him that this is not a wise idea. This is forgotten once the pick-pocket steals the money from the Inspector. In the end after he is captured we find out why the sergeant was reluctant to loan him money: it was a child's play toy, and the Inspector ended up in prison with the villain for counterfeit charges.
 * The Emperors New Groove has, towards the beginning of the film, Yzma and Kronk sneaking into the hidden laboratory. However, when Kronk pulls one of the two levers, it drops Yzma into a pit of crocodiles. She re-emerges, kicking away a crocodile in the process and asks "Why do we even have that lever?" before Kronk pulls the right lever and they enter the lab. Cut to the final conflict when Pacha and Kuzco reach the palace. The first scene we see is a wet Kuzco entering the chamber, kicking away a crocodile in the process and asking "Why does she even have that lever?"
 * And then when she's betrayed by Kronk, she uses a similar lever to get rid of him. This sets up another brick joke.
 * "Whoa! Who would have guessed that would lead me out here?"
 * "You know, in my defense, all your poisons look alike; you might want to think about relabeling some of them."
 * In the Justice League Unlimited episode "Dead Reckoning", Deadman hijacks Superman's body, cutting him off just as he's telling Wonder Woman about a place with "milkshakes so thick--". Halfway through the episode, Deadman finally leaves him, and Superman picks up right where he left off: "You have to eat them with a spoon! (Beat) ...Why am I in Africa?"
 * This joke was done all the more skillfully, as the first thing Deadman says immediately upon possessing Supes was "I need your help."

"Wendy: Ooh, you're quick."
 * Word of God says that they were going to do one about Amazo in the last episode but forgot. Amazo said that he was going to flee several light-years away during a battle against Grundy in one episode, and did, failing to return before the end of the episode. They were going to include a gag in the finale showing Amazo sitting on an asteroid somewhere, wondering whether or not it was safe to return.
 * In the movie version of Coraline, the eponymous character is offered some taffy-like candy in a bowl from her two elderly neighbors. The candy is so old and sticky, however, that she's unable to pry a single piece from the wad, and the candy winds up stuck to the ceiling, bowl and all. An unrelated conversation ensues between Coraline, Miss Spink, and Miss Forcible, distracting the viewer, and when Miss Spink declares, "Giraffes don't just fall from the sky, Miriam!" the candy comes unstuck and the bowl comes crashing down to everyone's great surprise.
 * In Monsters vs. Aliens, one feature of the war room is a Big Red Button that launches all the nukes in the United States... which is right next to an identical button that activates the latte machine. At the end of the film, after the first half of the credits, the buffoonish President pushes the wrong button.
 * In Tex Avery's "Symphony In Slang" (where Webster literally interprets a recent arrival's slang-filled story), there's a throwaway visualization of how Mary wouldn't talk to the guy. "The cat got her tongue." (It shows an innocent cat who immediately looks devious and holds out a tongue.) At the end, when asked why Webster couldn't make sense of it, the slang guy says, "What's the matter -- cat got your tongue?" We then see the same tongue-holding cat, only with a halo.
 * Bounty Hamster, "The Good, the Bad, and the Adorable": Some of the cute aliens accidentally go shooting off on a huge rocket engine and end up encircling the entire planet, to return just in time to run over the villain in the climax. Marion then turns to face the audience and says: "I bet you forgot about those guys, didn't you?"
 * During an episode of The Powerpuff Girls, the girls find Mojo Jojo in a store complaining about the firmness of a loaf of french bread, which he uses to bonk the store's owner over the head. After the girls beg Mojo to help them fight evil with evil and nearly failing, the Monster of the Week pushes Mojo's Berserk Button. Mojo finishes his attack by bonking him over the head with the loaf of french bread.
 * The Venture Brothers throws in a few of these now and then. The writers love screwing with the fans, so they deliberately dredge up details from forgettable episodes to use again later. A notably picture-perfect example is an episode in which Baron Underbheit tries to marry Dean, and one of his underlings gives the rest of Team Venture an invitation to the Baron's wedding to "Dawn" Venture - causing Hank to demand to know why his father has been hiding a sister from him. Cut to the finale of the next season, when Hank thinks that a meeting at "dawn" means that the boys will finally meet their sister, with no explanation to anyone who didn't remember the previous episode. In fact, the scene that sets up this joke is so random and at odds with in-episode continuity that this may have been planned from the start in some fashion.
 * Hank mentioning how he once jumped off the roof of the Venture Compound dressed as Batman in the season three finale. It was one of his many deaths shown in the first episode of season two. He then wondered if he might have just dreamed it.
 * If you're scratching your head on how the Monarch is invulnerable, recall the season 3 opener, where he shares a joke on how he managed to convince one Captain Sunshine that he was.
 * Captain Sunshine himself was first mentioned in a throwaway line all the way back in the first season finale. Other characters who appeared after being alluded to early on include Sgt. Hatred, Monstroso and Truckules.
 * In Disney's Aladdin sequel, The Return of Jafar, Jafar was using thief Abiz-Mal to help in his revenge scheme against Aladdin & Company. Abiz-Mal uses up his first two wishes in rapid succession (He wishes for a sunken treasure, so Jafar brings him to the bottom of the ocean and the second wish brings him back). At one point near the end, Abiz-Mal gets stuck in a tree. After Jafar is destroyed and the credits roll, we cut back to Abiz-Mal, still in the tree, saying "Does this mean I don't get my third wish?"
 * Catscratch has a particularly well done example. In the pilot, Gordon tries to convince Blik to not enter a barbecue contest by telling him an old Scottish tale that involves a seal woman deceiving some guy.
