Retarded Animal Babies

A Flash series created by David C. Lovelace, hosted on Newgrounds. Started out as a single short with the titular babies trying to teach the alphabet (similar to a Sesame Street spot, if the Sesame Street writers all did crack), and veered off into a series with the characters as actual characters, with actual storylines and dialog and stuff... sort of. Definitely not safe for work, or anyone who has problems with Funny Animals in sexual situations. Has also spawned a webcomic.

Tropes used in Retarded Animal Babies include:

Affably Evil: Satan.
The Alcoholic: Cat's stepdad.
Alcohol-Induced Idiocy: Happens on numerous occasions.
Anything That Moves - Puppy is, if allegedly straight, willing to screw just about anyone and anything, up to and including himself and a computer's floppy drive.
Art Style Dissonance
Black Comedy Rape
Bread, Eggs, Milk, Squick: For the Show and Tell, Donkey brought three potaters, a bucket full of pelicans and Satan (who brought a snow globe).
Brick Joke: Episode 18 has puppy (albeit unintentionally) pissing in Cat's face, something he said he would "try again later" in episode 3.
Call Back: In Episdoe 20, Puppy calls Donkey "Cap'n Pants", which was the latter's Superhero persona from episode 4.
Celeb Crush: Hamster is obsessed with Bruce Willis, and it's even stated in a few episodes that he wants him in that way.
Cloudcuckoolander: Hamster.
Comedic Sociopathy
Crap Saccharine World
Cringe Comedy
Cyberspace / Down the Rabbit Hole - The characters get sucked into the Internet in episode 10. Everyone is dressed like the Programs in Tron.
Dead Baby Comedy
Death by Childbirth - Puppy's mother, and he did not take it well when this particular memory resurfaced.
The Ditz: Donkey is the least intelligent of the bunch, and that's saying a lot.
Easter Egg - The episode titles are all clickable.
Eldritch Abomination: Bunny.
Famous Ancestor: It's revealed that Puppy is Sean Connery's son.
Funny Animals
The Internet Is for Porn - "I don't know about any vaginas, but my stepdad just got a cable modem." "It'll have to do."
Kissing Cousins: Puppy eventually marries his own cousin.
Negative Continuity: Justified. They grew up, and they realized how screwed up their world really is. Cat, who became a Mad Scientist of sorts, took them to a place outside normal time and space where they could spend all eternity blissfully ignorant and optimistic.
No More for Me - Donkey's reaction to seeing his future self.
Number of the Beast - In Episode 4, tapping 666 into the remote shows Satan eating children from a bowl. 999 gets you the same image upside-down.
Overly Long Gag - The phone call at the end of episode 21.
Refuge in Audacity
Refuge in Vulgarity
Rule of Funny - A donkey can shit lightning!
Satan - A recurring character.
Schedule Slip - 14 months between episodes 21 and 22.
Screw Yourself - Puppy's totally unsurprising reaction to seeing his future self.
Shout-Out - "Splunge" is a reference to a Monty Python's Flying Circus sketch.
Six Is Nine: Episode 4 features a fake TV screen as a bonus feature. Selecting Channel 666 leads to a video of Satan eating children from a bowl. Channel 999 is the same thing upside down.
Something Completely Different - Episode 4, which featured a TV remote control system to get to all sorts of extras.
Straight Man - Cat
Stylistic Suck
Subverted Kids Show - The original short.
Take That - Pico (Newgrounds' mascot) watching the cartoon (captioned in AOL-speak): "I watched this on Newgrounds, and I hated it. It rips off Happy Tree Friends. Blam this piece of shit!" (viewer then gets an anvil dropped on his head)
They Killed Kenny Again - As noted above, Bunny dies in (almost) every episode. The others sometimes die too (and the whole universe was even destroyed a couple times).
- Bunny even turned into a giant Cosmic Horror and attempted to end it all himself. His exact words, upon the "opening" of episode "21"(see the end of episode 20)? "Son of a bitch." "Kenny" was trying to stay dead, that time.
Tron Lines - The characters are depicted in Tron suits when they get sucked onto the Internet.
You Are What You Hate: Cat's openly homophobic, "queer"-bashing stepdad is gay. Cat's mom is actually a man in a wig.
