Anonymous Poster #1: Woody is stuck inside Sunnyside with the gang, and has just had his arm torn off by Lotso. Luckily, a rifle through the confiscated items drawer and a bit of duct tape later, Woody has a new arm — a Swiss Army knife duct-taped to his shoulder, Ash Williams style. Now what shall he do with his new arm? Bonus points if you can get Ken to call Woody's new arm "groovy". Anonymous Poster #2: I love you.
Fan Ficon crack. The easiest type of fanfic to write, and one of the hardest to write well.
Crack Fic is not merely humorous. In fact in many cases it doesn't have to be humorous. While it is similar to Alternate Universe Fic, in that they both change some fundamental aspect of the source material, the "something's different about this" idea is taken to the extreme. In its broadest sense, Crack Fic is any story whose premise and events would be completely implausible in Canon. These frequently include bizarre settings and explorations of improbable relationships between characters — not merely unlikely in canon, as in Foe Yay, but totally irrational and turned up a notch beyond that, as in Crack Pairing.
Crack Fic is often considered the result of a challenge, either from someone outside the author or from the author him/herself: "This idea is completely unworkable, but I bet I can make it work." The name stems from the notion that the author must have been ingesting some illegal substance just to think up the idea, let alone write it.
Our very own Pitch Generator is basically one giant Crack Fic crossover... generator.

Can your beer do this? Miller Lite did a whole campaign of these weird commercials in 2008, combining things like Sumo wresting and high diving and ice hockey with a beauty pageant.
The Marvel series What The—?! was all Crack Fic all the time: Superman (sorry, Superbman) showing up in the Fantastic Four book and making Sue fall for him due to his good looks as soon as he smiled at her to prove how much better he was. Wolverine trying to have a day off fishing but everyone showing up trying to get him to appear in their comics. Wolverine and the Punisher saving the rainforest...
The Pirates! Band of Misfits is pretty much a Crack Fic for real world history. Among other things we have Queen Victoria as an Ax-Crazy psychopath, all the world's leaders gathering together on a gigantic cruise ship to eat rare animals, Charles Darwin getting messed up with the eponymous group of pirates... yeah...
Bubba Ho-Tep features an elderly Elvis and JFK (whose brain has been transplanted into a black man's body, though he thinks he's just been dyed that color) fighting a cowboy mummy that sucks out people's souls through their anus. note Well, to be technical, "JFK" actually claims he was dyed that color, and that part of his brain was replaced with a little bag of sand.
There exists an obscure film called Geek Maggot Bingo. Of the entire film, the Word Salad Title is probably the least bizarre; there are cowboys, mad scientists, vampires, hunchbacks, transvestites, phones made of cardboard, cats covered with marker scribblings, the cheapest props and special effects you'll ever see (that are somehow strangely creative), at least a dozen samples of stolen music, and that barely scratches the surface of how screwed up this film is. Watch The Cinema Snob's review for a better idea.
Twilight is arguably a Crack Fic of Vampire Mythology. Furthermore, the fourth book, Breaking Dawn is arguably a Crack Fic of itself.
The Rocky HorrorDiscworldShow. Yes, it's official; made with the permission of Richard O'Brien and the enthusiastic encouragement of Terry Pratchett, the only performance took place at the 2010 Discworld Convention. Carrot and Angua are Brad and Janet, Lord Vetinari is Frank-N-Furter and Igor and Igorina are... oh, you guessed.
Don't forget the addition of noble warrior werewolves, rhinocerous-riding psychic ninjas, and the send-ups to/blatant parody rip-offs of George RR Martin's Westeros, which take the story off of crack just long enough to take a hit of the brown acid and follow it up with a few cool pints of heroin. And makes it all the more impressive that the story works incredibly well.
Tyra Banks' fantasy trilogy, Modelland could qualify. Set in a world where the fashion industry is Serious Business and supermodels themselves are Physical Gods, the whole society is structured on the chance for young girls to gather SMIZEs in order to be admitted to the eponymous Modelland, an academy teaching them how to become supermodels too. One cannot exactly talk of superpowered supermodels with a straight face.
The Glee episode "Comeback". To elaborate, it features Sue trying to commit suicide via gummy vitamins (on a show that would go on to treat sucide VERY seriously in a later arc), Mercedes and Rachel (two characters that are very different and barely interact with each other) singing a duet, a Justin Bieber tribute band, and a performance of a My Chemical Romance song while dressed as lumberjacks.
"Can't Smeg Won't Smeg" was the first feature of Red Dwarf Night, the Red DwarfTenth Anniversary Celebration. It is Red Dwarf as a cooking show, based on a real English cooking show. One full of the unintentional hilarity that comes of asking these characters to cook.
Spike stood at the door, slack-jawed for a few moments. The... thing... at the door gurgled pleasantly and tilted its head expectantly. He turned. "Um, Twilight? I'm hoping the door is for you..." —What About Crackle?
Super Smash Bros. Brawl. If canon could be Crack Fic, then Brawl would be the veritable god of the world of Crack Fic. The entire plot of the story mode makes absolutely no sense and the premise the game works on is that the characters are all actually "trophies" based on various Nintendo characters that have come to life and live in their own world, as playthings, and they face the possibility of being trapped in their non-living "trophy" forms forever. The reason it works well is because the characters don't have characteristics or personalities. The sole exception is Snake, and as such he acts completely out of character, always questioning the bizarre shit happening around him.
The bonus "External Gazer" short story on the Metal Gear Solid 2: Substance disc is a moving drama about Snake, Otacon and Mei Ling teaming up to battle a giant sea monster from another dimension. Mei Ling turns out to be secretly married to Solidus, and it gets weirder (and increasingly Genre Savvy) from there. It's all told from Snake's first-person point of view, and he's utterly deadpan about everything.
The premise of The Simpsons Game is that the eponymous family discover that they are part of a video game. Then they get into the game engine and save 8-bit counterparts of themselves from getting destroyed by Will Wright. Subsequently the characters get into different video games to get key cards that let them find their creator.
And then that game's Spiritual Successor and semi-sequel Project X Zone actually did end up making it Westward, which is quite a surprise...because it takes the Crack Fic nature of Namco X Capcom and turns it Up to Eleven with Sega characters added into the mix.
Eternal Sonata is a Japanese RPG about a dream that Fryderyk Chopin, a famous composer, had on his deathbed. In his dream, everyone who is terminally ill can practice magic, people literally turn into monsters, almost everyone's names are related to music (one of the main characters is named Allegretto, his brother is named Beat, and one of the villain's henchmen is named Guitar, for a few examples). and the environments just keep getting more and more abstract. Also, the ending is an utter Mind Screw.
Jack's third episode of Totally Non Canon Theater, Frigid McThunderbones. There are no words to describe it except "cracky". Well, and probably also "offensive" (at at least one point to any given reader).
There's a certain word game where one person starts a story with the first sentence, and each person in the group adds on another sentence. With certain groups of people competing to make the story even weirder than it was before, this can get pretty surreal. Also goes for certain improv games. The more formalized version is called "Consequences," and asks a different person to fill in one of the following, in order, then fold the paper so his entry is unreadable and pass to the next person. The items are 1. Man's Name 2. Woman's Name 3. Place 4. Reason they were there 5. What he said 6. How she replied 7. What happened. Hilarity Ensues.
Twilight Sparkles Secret Shipfic Folder has numerous examples referenced in the flavor text. But really, it's a game about a unicorn secretly shipping everyone in her life, so it's par for the course.
Peter Chimaera Book Of Hsitorical Fa Ffiction is 44 pages of gold. One story, Einstein's Theory of Justice, starts with Einstein "discovering" that he "invented" his Theory of Relativity and ends with a battle with Thomas Edison who used the theory to time travel to that moment to steal it for himself and take the credit. It really picks up once Edison recruits the mummy of Julius Caesar to fight Einstein.
The Door is a TaleSpin/Stargate SG-1 crossover that actually makes sense. Yes, furries and the Stargate universe and it makes sense. Worth a look if you like both franchises.
Oddly, his stories also tend to take on a serious note in later chapters, generally around chapter 3 or 4, with things like plot and character development appearing, without in any way reducing the crack level.
There is a crossover between Dragon Ball Z and The Diary of a Young Girl. Anne lives, falls in love with Goku, and Hitler turns Super Saiyan shortly before Goku vaporizes him. One gets the feeling that this was inspired by an O.D. on a combination of Psychadelics, Ritalin, and bad ingenuity. The fic in question can be found here. It is possible that its genesis lay not in drugs but in a misguided middle schooler coming home from school after learning about the holocaust, thinking, "Man, Hitler sucks! Goku should kick his ass!" And then he set his eyes on the computer, and one of the great legends of fanfiction was born. The fic is read by Bennett The Sage here: . And believe it or not, this kind of already happened in canon. It's called the 12th movie, Dragon Ball Z: Fusion Reborn. No, seriously. Hitler got revived in the 12th movie, and Goten and Trunks kicked his ass in Saiyajin form. It's only in the uncut DVD release. All TV Syndications edit out all scenes with Hitler.
There is a crossover between Seinfeld and Higurashi no Naku Koro ni in which the entire village of Hinamizawa is somehow moved right next to Jerry's apartment. It featured the main characters of both shows interacting in various ways, the most notable being Kramer and Rika falling in love. The fic ended with Newman becoming possessed by Hinamizawa syndrome and murdering Rika by torturing her. Upon finding the dead body, the fic ended with Kramer shedding a Single Tear. Unfortunately, it was posted on someone's private website that has since been taken down.
Someone decided to cross Haruhi Suzumiya with TV Tropes, and later added in the cast of Higurashi no Naku Koro ni. Whilst it makes perfect sense when you read it, telling someone anything from the story itself is... odd. Like mentioning how Kyon, Nagato, and Tsuruya managed to defeat 24 yakuza in a fight without getting harmed. It's called Kyon Big Damn Hero.
Gurren Jesus is a story where Jesus Christ saves Kamina. Then they ride motorcycles and fight nazis, including Hitler dressed up as Chester Cheetah. And it is awesome. It can't get any crazier than this.
Except the sequel can. And it's an evenbigger crossover. And now they're fighting soviets for some reason.
Robo Bando is an Elfen Lied Crack Fic that crossovers with Real Life, Doug, CatDog, Sonichu and many other things. The story begins when Lucy's dead dog grants Bando cybernetic parts to kill Lucy. A few chapters and one world blow up later, he gains Doug as a sidekick after saving him from CatDog and becomes BFFs with DC Comics' Grant Morrison.
One of Comics Nix's finest works is called The Day the Men Found Love. Batman teams up with Robocop to find a killer, but they also... find love. Stranger yet is the one known as Severus Snape, Professor and Lover, in which Professor Snape quits his job at Hogwarts to teach in Teletubby Land. Yes, seriously. Snape's lessons are not about magic.
Shinji And Warhammer 40 K. Shinji Ikari (Butt Monkey) gets a Warhammer 40,000 set at age 6 or so, and it makes him akin to the God-Emperor of Man; that is, inhumanly badass. He turns Eva 01 into a Titan. Kamina would be proud. When it comes to Shinji becoming the Emperor, all signs point to "yes." Later, Shinji leads an army of Terminators, super tanks, and psychics against a horde of zombies. Well, there's something in every chapter. Also, Rei gets orky. The author, on a forum where he has the story proof-read, made a comment that he believed that he has been writing Ritsuko too flat, and that he might have her break through as a Spark. The actual page for this sums it up:
Thousand Shinji and its even more crack-tastic sequel The Open Door, To pick one plot line out off The Open Door: A daemon (who eats souls, and kills people with tentacles) named Lars and Skuld cause an industrial revolution, change the nature of magic and raise a child. Oh, and Skuld is technically the father.
There is a Narutofanfic about what allegedly happened during Itachi's story. Where to start...? Well, he accidentally killed his friend during a spar, accidentally killed the entire clan (after he used the wrong side of his sword to threaten them with... oops)... the list goes on. And his super torture move? He distracts the target then screams in their face. First person to guess what goes here gets a cookie!
All You Need Is Love from the Death Note fandom has Light/Naomi Misora as the pairing, makes Naomi the narrator, and just takes what it wants. One of the best Crack Fics in existence despite butchering of grammar.
A Bleach fanfic version of this: Love and the Art of War. Nanao X Kenpachi Zaraki. In the words of the author, "Nanao X ...Zaraki? I have no excuse, explanation, or defense of this pairing whatsoever. So very, very sorry. The crack! It burns!" And it's actually good.
Slope, a Death Note Crack Fic. This fic is only particularly funny due to its radically understated final line.
In Uninvited Guests, Yachiru burns entire 11th division while baking a cake, Hitsugaya talks with a secretly evil imaginary cat, and Godzilla appears for some reason. The catch? Once you read it, everything makes sense... a lot. This is one of rare Crack Fic that manages to be both insane yet remarkably reasonable. Also, it's the closest and the best thing we have to BleachAbridged Series.
This lovely Axis Powers Hetalia fic. The plot involves Austria's mole coming to life, and causing mayhem. Yes, you read that correctly. His mole. The author, though, fully acknoledges the weirdness, and the characters frequently break the fourth wall to comment on how strange the events happening are, and there are many pop culture refrences. The full title? The extremely amazing ballad of Austria's annoying mole and their amazing adventures when said mole comes to life: An Axis Powers HetaliaTroll Fic of EPICNESS!!! (a.k.a. the shorter title, "The Annoying Mole, a HetaliaTroll Fic").
Sexy Mens: Butler and Demon Lord is a parody of all yaoi fanfiction, Ouran Highschool Host Club, and Kuroshitsujii. Kyoya takes on a contract to have Sebastian as a servant (having the contractor's symbol tattooed on his ass) and matters escalate to sex at light speed. Includes Sebastian doing DDR, Kyoya streaking, countless yaoi jokes, many video game references, teabagging and other things with a ridiculous level of awesome. It also has what might be the best (and least sexy) yaoi scene ever written.
"AND THEN HE STARTED DICKING BY PUTTING HIS DICK INTO THE DICKHOLE WHERE THE DICKS GO. DICKS FLAPPED EVERYWHERE, AND THERE WAS MORE GRUNTING AND GROANING THAN AT A WOMEN'S WORLD CHAMPIONSHIP TENNIS MATCH." And that's only the beginning...
Star Wars Light In Dark Time is a massive crossover fic, detailing Luke's adventures through multiple other film series, aided by the Doctor, Marty McFly and Doc Brown, and his friends. Filled with alternate timelines, fictional universes, cameos, and an insane shrek. In the first two chapters alone, one character dies three times.
As a side effect of having such a large fandom, Harry Potter has more Crack Fics than you can shake a stick at.
We simply cannot have a page about Crack Fics without mentioning the incomparable My Immortal.
The Misadventures of Draco Malfoy, Ferret Summary: Snape turns Draco into a ferret for his own protection. He would've been safer with the Dark Lord. Warnings: m'preg, multiple beastialities, and Gryffindors. This is a hilarious romp on the weird side of what happens when a half-baked plan and a little magic go horribly awry. Snape turned Draco into a female ferret by mistake. I'm sure you can guess what happens.
There is a legend of Polish Internet in the form of Magical Adventures of Winnie the Pooh story cycle. The characters spend most of their time boozing cheap wines or whoring, Owl is a pedophile, Christopher Robin a Flamboyant Gay, Eeyore's real name is "Hannibal Lektor", and Piglet is proud to wield the longest member in the forest (which happens — the forest, not the member, duh — to be located somewhere in Poland, presumably east of Warsaw).
Six Days The Animorphs Were Idiots, by one of the co-authors of Cinnamon Bunzuh! is an Animorphs fanfiction that features, among other things, Visser Three adopting cats, Cassie forming a whale-worshipping cult, and Rachel finally getting some much needed therapy. Notable for keeping everyone very much in character, despite the odd turn of events.
Even her more "serious" fanfic edges into this, since they're all set in the same canon. For instance, The Other Attack (plot: the five highest-ranking Vissers are put up against a bunch of alien bandits) has such gems as Visser Three acting like a Tsundere for Visser One, Visser Two being a complete moron (Visser Three, no genius himself, repeatedly questions how Two outranks him), and Visser Five being obsessed with her host and daughter. Or consider the Controller Chronicles, a series of short fics about Human-Controllers and their Yeerks: half of them are quite serious, and the other half are basically efforts to make Chapman's life even more miserable.
Hear Me Hodor is A Song Of Ice and Fire/ Game of Thrones crack fic, where Jaime Lannister and Hodor are forced to get married. Hodor is a giant, mute, ugly stupid stable hand who cannot speak, and Jaime is the strongest warrior in the realm. To add insult to injury, Hodor is actually Jaime's brother as well, in this fic. Furthermore, Hodor is absolutely and undyingly in love with Jaime, but the knight does not return his affection. Hodor won't take no for an answer. It includes many yaoi jokes, and his hilarious as hell.
"In the Game of Thrones, you win or you die, but what happens if a giant, semi-mute dung shoveller grabs hold of you and forces you into a romantically suggestive dance with him? Out of winning and dying, Jaime supposed it was a damn slight closer to dying." - Jaime on Hodor forcing him into a tango.
Scully Is a Highlander. Featuring Mulder bemoaning the fact that since Scully got the cool trenchcoat with hideaway sword, he's been demoted to comic relief.
Counts of Blood, a crossover between Buffy the Vampire Slayer and The Muppets with Count von Count visiting his old friend The Master in Sunnydale. Let's just say that the Count is not entirely sane, nor is he kid-friendly. It's wonderful. If Sesame Street and The Muppet Show had never been aired, and the word "frog" swapped with, say, "reporter", it would be just another Buffy fic — albeit well written.
The Master frowned, moving towards his guest. "I have been trying to be a bit less excessive about object lessons this century. I don't want another mathematician like that fellow."
One purple hand waved, and there smaller vampire shrugged. "I have medications for that now. There shouldn't be another situation like that as long as I take my pills. Thirty six little green pills for a twelve day visit."
"Much better than three mathematicians in several hundred pieces," the Master shook his head.
"One mathematician, in one hundred and sewen boxes. With a diagram of where they all went," the Count corrected. "I let his assistant go."
Series/Merlin fanfic A Very Hairy Situation. Gwaine's hair is so fabulous it has the power to turn people gay. And Arthur prances.
Stargate Atlantis fandom has a thing about penguins, or more specifically, about turning its characters into penguins. John Sheppard, Rodney McKay, and Carson Beckett have all turned into penguins (the former two in multiple works). And then there was that time when McKay was a dinosaur. Or when Sheppard was a rainbow and McKay was a unicorn. Or the one where they were girl scout cookies. Socks. Ice cubes.
The Fourth Wall series, a Supernatural Crack Fic that features Sam being sad because everyone's jumped on the Dean/Castiel bandwagon and no fanfiction is being written about him anymore, Dean finally realising that he does love that trenchcoat-wearing Angel, Castiel eating everything remotely sugary in sight and Lucifer playing poker for M&Ms. It's amazing.
The Kink Meme for the Sherlock fandom spawned a running joke that's managed to filter through into a number of non-crack fanfics regarding Anderson having an... interest in dinosaurs. Not as popular, but also present is the idea that John Watson is in love with jam, and that his character is made of kittens (more to do with the fact the actor that plays him is Martin Freeman).
This Castlevania crack fic pitches a transvestite Alucard fighting a dinosaur Dracula with a sudden appearance of characters from Sex and the City. Filled with non-sequitur's, pop culture references, self referencing humor and extensive commentary from the author.
The Not so Villainous Duo, a The Legend of Zelda Crack Fic where Ganondorf blackmails Vaati into stopping Link. They spend 17 chapters on increasingly random and failed attempts and eventually get defeated by Dark Link, who was hired to do so by the author
Lexaeus Loves Hot Topic, a Kingdom Hearts fanfic with appearances by Harry Potter characters. The already strange premise appears to be characters from the two franchises meeting in a normal, 21st-century American shopping mall. The execution, though, is what really sells it as Crack Fic, being a (to be very charitable) disjointed stream-of-consciousness narrative, eschewing typical structure in favor of imagery through disjointed phrases and occasional syntactic contradictions, such as a narrative sentence becoming dialogue halfway through. A descriptor might almost be My Immortal and Those Lacking SpinesmeetFinnegan's Wake.
Stray is relatively down to earth, apart from the homemade time machine, a rather trippy sequence in the afterlife, and the fact that it's all done in the service of an epic love affair between a character from the 1960s and a character from the 2000s who have no on-screen interactions in the source material.
The Hitchhikers Guide to the Stage of History, a Soul Series fanfic, is one of those rare well-written Crack Fics. It begins with Yoshimitsu being mistaken for Jesus, and ends with Setsuka trying to destroy the world with the Infinite Impobability Drive, and a climactic battle with CATS for no good reason.
Once upon a time a fan challenged fanfic writers to write the craziest story that they could come up with so that he could post it on his site. The site is long gone, taking the stories with it. One of the stories was a little gem called Empire Evil, a cross between Resident Evil and Final Fantasy VI.
Final Fantasy XVI: Revenge of the Fishglobe! — One review puts it this way: "Revenge of the Fishglobe is not intelligent, nor sophisticated, nor cleverly crafted. But silly and stupid as it is, I have seldom laughed more in any given 5 minutes than when I was reading this fic." The author himself puts it this way: "If this story makes any sense to you, you need serious professional help."
Dissidia: Final Fantasy, because of its nature as a Massively Multiplayer Crossover for the whole Final Fantasymultiverse, could count on its own as one of the "official examples" above... but the sequel (although plot-wise it's more of a prequel) has a "quest editor" mode, which, as you can guess, can allow the player to, technically, write his own fan-fic and then make it playable. Which, of course, is awesome. Until you take Sturgeon's Law into account, since it kicks in as soon as one of the first quests (if not the first) made for the game gets uploaded on Youtube, and then you find out that, in the uploader's own words, it's about Tifa's skirt.
On the official Dwarf Fortress forums dwells a Crossover between Dwarf Fortress and Star Control II which purports to explain the origin of the "Adamantine Space Elevator" (a spike of adamantine ascending thousands of z-levels into the sky of one DF-generated world, probably due to an amusing Good Bad Bug). It's here.
Omake started out as an attempt to be serious, but when a joke at the end of the first chapter takes on with fans on deviantART, the entire fanfic got a whole new makeover in storytelling style. Now instead of an AU of Final Fantasy Dissidia where the Ivalice from Final Fantasy Tactics has representatives, every character is whisked away to a very, VERY crack-induced Ivalice that makes absolutely no sense. Includes a Nyan cat cosplaying Squall Leonheart summoning a TOASTER shaped like a Jumbo Cactuar that shoots waffles and burritos. And that's just the tip of the iceberg...
Zombie Madness! is a Mario fic that features a crap ton of gore, love triangles, insanity, stupidity, characters acting OOC, and even more insanity.
Super Mario Bros Dark Horizon. Also known as the only fan game which has Adolf Hitler and the Nazis invading the Mushroom Kingdom, Mario trying to stop them with power ups and Mario physics, Mario driving tanks around and shooting the heck out of everything, Osama Bin Laden as a boss in an area based off Afghanistan... and Hitler turning Super Saiyan with the power of super science/magic! Find it here.
Similarly, Super Mario Bros The Revenge of the Walrus could probably count here too. Evil walruses (from Mario's Wacky Worlds) invade the Mushroom Kingdom and it's up to Mario to stop them by answering quiz questions, exploring an insane drug trip filled with cheesy clip art and fighting an evil walrus king that turns into a tank while One Winged Angel from Final Fantasy VII plays in the background. And Hitler's a secret boss.
Paranoia Hides In Every Corner, is a fanfic which evolves around Pikmin, which is a twisted side of the Pikmin 2 story. It contains Olimar as a Sir Swears-a-Lot character and a cannibal, Louie a Too Dumb to Live and Emo character, and the President even worse than him in stupidity, who Olimar and Louie later kills and Olimar eats him up. There are also three pikmin along the way; A stupid Gass Hole purple pikmin named Klutzy, an Ax-Crazy yellow pikmin named Picky and the Only Sane Man blue pikmin Cam. The story is so bizarre and random that you will most likely be completely weirded out while reading it. According to the author, it was all intentional.
Toho Kingdom Toons: Well, aside from the obvious fact that the premise is based around Godzilla characters acting like humans, the show, especially recently, has gotten insane. Among other things, Gabara wears a Emperor Palpatine cloak and is a bumbling Cloudcuckoolander, Gabara and Monster X are movie critics, Godzilla is Happily Married to Cthulhu, Spacegodzilla hosts a talk show, there's a flying pirate ship called the S.S. Bootylicious, and Biollante fights Katz Kandy in space with a reference to LOLCats. Yes, I shit you not.
The web series School of Thrones, which asks the question: "What if A Song of Ice and Fire were a teenage drama series about cliques battling it out in high school to decide who became prom king and queen?" It even has a pen-and-paper version of the show's famous intro sequence. Hipster!Starks and Nerdy!Stannis ensues.
The Transformers Animated Crack Fic You Never ARGH WHAT AM I WEARING? featured Starscream having sex with Blitzwing, a character with multiple personalities. Blitzwing was wearing high heels, fishnet tights, and a thong all through the fanfic. What made the fanfic even more crack was finding out which personality was really in charge when it started.
Beast Wars has its own Crack Fic in Beast Wars: Make it Real Big. Optimus Primal evolves into Rapidash, Cheetor dies but continues to contribute to the dialogue via gas emissions and the character of Airazor turns out to be a cleverly disguised "Airazor Bomb."
Osama's Last Stand by Fireand'chutes777 is one of those rare examples of a Crack Fic done right. The basic premise is simple: Action Girl heroine Kim Possible is called in by President Bush after Al-Qaeda attacks America on April 23rd, 2007 to kick aforementioned terrorist organization to the curb (hence the title). It should be an exaggerated stream of Girl Power and Eagleland patriotism, it should have terrible grammar and be wrapped up in one chapter, it should spit in the face of basic physics, but what happened instead was a 128,000 word novel that would not look out of place at all in a book store with the name Tom Clancy printed in big bold letters on the front (ironic in that the author hadn't even touched a Tom Clancy book until he was done with the third story in his series). Even though the author himself admits the reader needs to apply a healthy dose of Willing Suspension of Disbelief to get past some of the set-up, once one does it's a very enjoyable story for any technothriller fan.
William Country of Total Drama fanworks is a literal Crack Fic in that the animator reportedly did drugs while making it. The plot itself is fairly straightforward (although it does involve a character in a relationship with an Original Character who looks like himself), but there are countless unusual moments, related to the plot or otherwise, and bizarre background events (such as a bunch of buses flipping around while Chris is narrating). All in all, it's somewhat surreal. It's also notable for being the first — and so far, possibly only — full length Fan Film of Total Drama, measuring at about ninety minutes should you combine all its parts together. That is, if you can find all the parts, as often times they get taken down after being uploaded.
Bart The General, a nonsensical quartet of The Simpsons videos where Toadfish from Neighbors crosses over and Marge cheats on Homer with him. The first episode is straightforeward, if having Deranged Animation, but subsequent episodes show more of the city (renamed from Springfield to Duckberg), and showcase that it's nothing like Simpsons at all. The third episode is complete and utter Mind Screw that hops from one subject to another and seems to have characters getting in and out of situations with no explanation given.
Iron Man: Kindergarten Adventures is proclaimed by the author to be crack, probably because the West Virginia Mothman becomes central to the plot in the last chapter.
Horny Lil Devils takes the Horny Devils trope and applies it to the entire cast of Kim Possible. Notable for keeping the characters recognizable while totally ignoring everything in canon (chapter five is titled: "Punching Canon in the Throat). It's utterly hysterical from start to finish. Too bad it seems to be a Dead Fic, though.
On the same page as Nazi fan fictions, there is a rare historical Crack Fic on the internet about a paring between a Mary Sue type character and Josef Mengele. Let that sink in for a while. A story full of IKEA Erotica featuring a mutant Mary Sue and Josef Mengele.
This fanfic swaps Kaho (Cardcaptor Sakura) and Dark Helmet (Spaceballs). Important to the plot: The Eye of Autochthon.
From a similar generator comes this challenge:
Write crossover fanfiction combining South Park and The Chronicles of Narnia. The story should use an overdose as a plot device! (The poster added this subcaption: "If C.S. Lewis isn't doing at least 120 rpm in his grave by the time this fic is finished then you didn't do it right!")
