Some things fans write down can get [[BigLippedAlligatorMoment downright weird]], [[CrackPairing shipping]] and [[FetishFuel kink]] preferences aside.
----
* ''[[Fanfic/RealityChecksNyxverse Nyx's Family]]'' has Chapter 11, wherein Market Forces, an economist in the employ of the Royal Sisters lectures the audience on the virtues of free market capitalism, labels [[ArtisticLicenseHistory prerevolutionary France's Ancien Regime as an example of the evil and oppresive nature of socialism]] before we are treated to [[BigLIppedAlligatorMoment a flashback of Celestia and Luna using a magic mirror to consult HUMAN economists]] in order to create Equestria's economic system [[AuthorFilibuster All of the consulted economists are libertarian free market Austrian school economists like Hayek or Von Mises. Not one mainstream economist like Keynes, Galbraith, or even Milton Friedman is consulted]]. After [[InternetBackdraft a particularly hellacious case of Internet Backdraft exploded in the comments]], the author made a point of never ever referring to the events of this chapter in the rest of the story or any of its sequels.
* ''FanFic/QueenOfAllOni'' has a very strange DreamSequence in the third interlude chapter, it has to be read to be believed!
* ''Fanfic/ChaosIsVeryGood'' is composed of these, not surpringly. And yet, [[spoiler: the Mayor's ghost talking]] makes the whole thing seem sane and sound in comparation.
* Many stories have Cid Highwind from ''VideoGame/FinalFantasyVII'' randomly complain about people interrupting ''Series/TheDukesOfHazzard''... and then the show is never mentioned again and most of the time the plot continues as usual.
* ''{{Fanfic/Bart the General}}'', despite making little sense to begin with, has a few scenes like this, such as one when [[Series/{{House}} House]] climbs a water tower and gets his cane broken by an icicle, and a scene where Barton wakes up in an underwater vault with a strange gauge.
* Subverted in ''LatiasJourney'' with the [[ParodySue Berry Stoo]] fight, the RPG arc, and the [[spoiler: battle between the Pokérangers, Team Rocket and the Tyrantron]]. Not only does Ash get a rematch with Stoo later on, but [[spoiler: Mewgle becomes [[strike: TheDragon]] TheManBehindTheMan, and the origin of the Pokerangers becomes an important plot point]].
** Played straight when [[spoiler:Giovanni's body (working for Deoxys) is trying to interrupt Rayquaza's resurrection]] and stumbles onto the set of a game show for no good reason.
*** Not exactly, Copernicus(the ghost) is mentioned in the following scene, by characters who had NOT been there. He is one of the guard ghosts, and a character from another fanfic author.
* [[FanFic/DiddyKongRacing5000 "Watch for moving Nintendo 64 logos."]]
* In the ''[[Anime/NeonGenesisEvangelion Evangelion]]'' GagDub ''[[http://sokodei.com/redeath/ Evangelion: ReDeath]]'', [[Anime/{{Pokemon}} Pikachu]] attacks NERV. However, the following scene acts like an AMV for ''Pokémon'' set to the [[Music/{{ACDC}} AC/DC]] song [[DoubleEntendre "Big Balls"]], and there's not much of a focus on Pikachu, but rather James, another character from ''Pokémon''. After the "AMV" is done, ANOTHER random anime is introduced -- ''TenchiMuyo!'' The cast of ''Tenchi Muyo!'' is quickly killed off by Pikachu, and the plot returns. ...yeaaah...
* One of Stephen Ratliff's later MarrissaPicard stories, 'Winning Love By Daylight', has this bizarre (even by Ratliff standards) scene where Jay Gordon and the resident psychiatrist Martin are talking about Marrissa's problems in a restaurant when the narration casually mentions a monster walking in to the place. Just as suddenly, two of the 24th Century's version of the [[Anime/SailorMoon Sailor Scouts]] show up (please note that outside this scene, Ratliff's stories are ''Series/StarTrekTheNextGeneration'' fanfic and don't usually cross over with ''Sailor Moon'' or anything else) -- one of them being a half-Klingon girl. The two vanquish the monster and leave. Jay and Martin comment on the weirdness, and then it's never mentioned again.
* Marty [=McFly=] makes a cameo in ''FanFic/MyImmortal''. Yes, ''that'' [[Film/BackToTheFuture Marty McFly]]. It's best not to try to think about that.
** Actually, it's probably best that you don't think about My Immortal period.
** My Immortal is full of them. Dobby is one.
** The hacker's chapter and [[spoiler:Draco]]'s suicide are two of the most egregious examples.
* While ''Naruto Veangance Revelaitons'' is not very coherent, the dream sequence Ronan has in Chapter 47 in which he, among other things, comes face to face with the author's stepbrother, is one ''by the author's own admission''.
* The ''WesternAnimation/TotalDramaIsland'' FanFilm ''FanFic/WilliamCountry'' has several, such as Cody smoking or a completely random cut away to a ''GuitarHero''-esque game.
* One SoBadItsGood Franchise/SailorMoon fanfic has a random cutaway to [[Manga/AzumangaDaioh Sakaki, Chiyo and Osaka]] ''right in the middle of a battle scene.'' Should also be noted that the fic is otherwise not a crossover.
* ThirtyHs is almost entirely composed of this, which, in combination with its abuse of PurpleProse, makes it {{egregious}}ly hilarious. Whether [[TrollFic this is intentional]] or [[SoBadItsGood not]] is [[PoesLaw impossible to tell]].
* In chapter 1 of ''FanFic/FrigidWindsAndBurningHearts'', Princess Luna knocks a bowl of soup into Prince Blueblood's face. There is then a brief, inexplicable cutaway to the bowl of soup's dying thoughts, as it hopes to have earned a place alongside Sir Lint-a-Lot and Rocky in Inanimate Object Heaven. To say this is out of place in a story that takes itself so seriously it's painful is to make a gross understatement, and this is never mentioned again.
* The MadnessMantra in chapter 1 of ''[[http://www.fanfiction.net/s/3025869 The Grim EDventures of Ed, Edd, n Eddy]]''. Sure, it's taken from [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy one of the works involved]], but it's still a BLAM.
* ''WebAnimation/TurnaboutStorm'' has [[ShoutOut a reference]] to the infamous DarkFic ''FanFic/{{Cupcakes}}'' involving a creepy zoom, eerie music, and the background turning red; only for then to have everything turn back to normal and the investigation continuing like nothing happened. What triggered this reference you may be asking? A discussion about freaking ''ladders'' [[InsistentTerminology ...or was it about step ladders?]]
* ''Fanfic/CalvinAndHobbesTheSeries'' has the titular duo doing a brief (as in ''two seconds'') hat and cane dance at the end of the second episode.
* The "Fanfic Mode" version of episode 5 of NonePiece. And that is '''[[SerialEscalation SAYING]]''' something.
* Subverted at one point in Fanfic/JakeEnglishsMysteriousTheaterOfScientificRomanceFromTheYear3000, where [[MakesJustAsMuchSenseInContext Andrew Ryan and Zachary Comstock suddenly appear in front of rose and company to belt out an expository rap duet.]] It's actually a brick joke from season 3, where sollux joked that this would happen in season 4. [[spoiler:Given that he's the Seer of Doom in Homestuck, they probably should have taken this more seriously.]]
** Also subverted when [[PokemonXY Valarie]] shows up in a throwaway gag. [[spoiler:This turns out to have been the StartOfDarkness that led to her becoming Monarch.]]
* This is an EnforcedTrope during the Cowboy Guys' introduction in ''[[http://www.fimfiction.net/story/68515 Paper Mario: The Land of Harmony]]'' where they spoil events that happen later in the game/story [[NoFourthWall shattering the fourth wall whilst doing so.]]
