History HilariousInHindsight / WesternAnimation

* ''HilariousInHindsight/SpiderManTheAnimatedSeries''

*** We later learn in "Operation PROM" [[ADateWithRosiePalms what that means.]]

* ''HilariousInHindsight/SuperMarioBros''

* In the 1938 short ''Daffy Duck in Hollywood'', Daffy puts together footage from several different films to make a bizarre patchwork feature that heavily resembles today's WebAnimation/YouTubePoop videos.

*** Speaking of MLP, there's a villain who uses a robot unicorn that shoots lasers to commit crime. You know it's funny when you realize that [[Creator/TaraStrong Sari's VA]] voices a [[WesternAnimation/MyLittlePonyFriendshipIsMagic certain purple unicorn]].
*** Also in ''Human Error Pt. 2'', There are quotes of "So much for the element of surprise" and "Just do it!" which become something [[Creator/TaraStrong Sari's voice actor]] [[Recap/MyLittlePonyFriendshipisMagicS4E6PowerPonies would say later.]] Also "Just do it!" becomes something [[Creator/ShiaLaBeouf Sam Witwicky]] says( and no, the [[{{Film/Transformers}} Sam from the other Transformers]]).
** There's something funny about how back in Beast Wars, Creator/GaryChalk voiced G1 Megatron but in this series Creator/DavidKaye now voices Optimus Prime. Deliciously ironic yeeesss?

** In one episode, Bowser tries to force Peach to marry him. [[Anime/TheGreatMissionToSavePrincessPeach This idea]] [[ComicBook/SuperMarioAdventures was already used]] [[VideoGame/SuperPaperMario multiple]] [[VideoGame/SuperMarioOdyssey times.]] Although the tux Bowser wears is VERY similar to the one he would wear in VideoGame/SuperMarioOdyssey.
** In the episode, “The Unzappables”, Al Koopone (King Koopa as one of his many alter egos) destroys a safe by going Bo-bomb Bowling. This was 9 years before the release of VideoGame/TheLegendOfZeldaOcarinaOfTime, which included the Bombchu Bowling mini-game, in which you roll bombs into holes in a wall to win rupees, which the safe has a very similar resemblance to.

** [[WesternAnimation/FamilyGuyPresentsLaughItUpFuzzball The Star Wars parodies]] that the show did are much funnier now that Disney owns both Franchise/StarWars ''and'' Family Guy.

* "I Never Met the Dead Man" features a cutaway to an episode of ''The Scooby-Doo Murder Files''. The joke is obvious; plopping the traditionally silly, family-friendly cast of ''Franchise/ScoobyDoo'' into a dark, adult crime drama with gruesome murders and truly monstrous antagonists is a pretty silly thing to do and would be very hard to take seriously! Except in 2022, Warner Bros. announced ''Velma'', an HBO Max Original spinoff of ''Scooby-Doo'' that... takes the traditionally silly, family-friendly character of Velma and plops her down in a dark, adult crime drama with gruesome murders and truly monstrous antagonists.

* ''WesternAnimation/DuckDodgers'' :

** One of the guest stars in the show was a post-[[Film/HighSchoolMusical High School Musical]] Creator/ZacEfron, who played a lifeguard named Davey Hunkerhoff as a send-up to Series/Baywatch. Flash forward to 2017, and Zac stars in the [[Film/Baywatch2017 big-screen remake of Baywatch]] as one of the lifeguards.

* ''WesternAnimation/TheSecretOfAnastasia'' (a [[TheMockbuster Mockbuster]] of WesternAnimation/{{Anastasia}}) has a plot point where Anastasia has two men interested in her, [[spoiler: and is unaware that one of them is a PrinceCharmless who's only using her to get the throne]]. [[WesternAnimation/Frozen2013 Sounds familiar, doesn't it]]?

* One episode of ''WesternAnimation/TheLooneyTunesShow'' has a scene where Daffy is looking for a tiny license plate with his name on it and finds a plate with the name Darvin instead; he then proceeds to question [[WhoNamesTheirKidDude why anyone would name their kid that]]. Funny enough, in the ''Looney Tunes'' fandom, fans who ship Daffy with [[HoYay Marvin the]] [[FanPreferredCouple Martian]] typically call the ship [[PortmanteauCoupleName Dar]][[NamesTheSame vin]].

* On ''WesternAnimation/MightyDucksTheAnimatedSeries'', [[TheSmartGuy Tonya]]'s WeaponOfChoice is called the [[Franchise/MassEffect Omnitool]]. Cue jokes about Commander Shepard working with the Ducks when the show became widely available for the first time in decades due to Creator/DisneyPlus launching in late 2019. For bonus points, another member of the team, Mallory, shares both her [[Creator/JenniferHale voice actor]] and [[FieryRedHead appearance/temperment]] with the default [[FanNickname FemShep]].

* The Thanksgiving episode in which Joe's long-lost son comes back from the Iraq War (and most of the episode consists of the characters arguing about the moral and ethical stance of why America had any business in the country) goes from being "WereStillRelevantDammit" to an UnintentionalPeriodPiece thanks to the Iraq War ending a month after the episode's premiere.

** Another episode gave us the {{memetic|mutation}} "[[https://www.youtube.com/watch?v=IVXJmfd3cmg And nothing of value was lost]]" quip when a flaming parade float crashes into a theatre playing ''Theatre/{{Cats}}'' and blows it to kingdom come. After the [[Film/{{Cats}} film adaptation]] crash-landed into theatres with its downright ''abysmal'' critical reception and gained notoriety for its UncannyValley characters, the clip has only become funnier.

* The 1990s ''WesternAnimation/XMen'' cartoon featured a number of HoYay moments between ComicBook/{{Magneto}} and ComicBook/ProfessorX, especially in the series finale. A few years later, openly gay actor Creator/IanMcKellen was cast as Magneto in the live-action films.

* "I Never Met the Dead Man" features a cutaway to an episode of ''The Scooby-Doo Murder Files''. The joke is pretty obvious; plopping the traditionally family-friendly cast of ''Franchise/ScoobyDoo'' into a dark, adult crime drama with gruesome murders and truly monstrous antagonists is a pretty silly thing to do and would be very hard to take seriously! Except in 2022, Warner Bros. announced ''Velma'', an HBO Max Original spinoff of ''Scooby-Doo'' that... takes the traditionally family-friendly character of Velma and plops her down in a dark, adult crime drama with gruesome murders and truly monstrous antagonists.
