History HilariousInHindsight / WesternAnimation

** In "X-Ternally Yours", Gambit gets hurt because of the wedding ring that Bella Donna forced him to wear. When Wolverine tries to remove the ring, he quips to Gambit "You ain't the marrying kind." Many years later, in ''ComicBook/XMenGold'', [[spoiler:Gambit ends up marrying Rogue after Kitty Pride got cold feet over her own wedding with Colossus]].

* ''HilariousInHindsight/{{Rupert}}''

* ''WesternAnimation/TheToolStreetGang'', a FailedTVPilot from 2001, managed to preempt ''WesternAnimation/HandyManny'' (which came out in 2006) on so many things it's, quite frankly, absurd:

** And, to top it all off, Tap and Pat the hammers have each other's name [[SdrawkcabNamespelled backwards]].

** On a slightly different Disney-related note, the episode "Lois Kills Stewie" has Stewie (in a simulation) becoming the president of the United States and banning all straight-to-video Disney sequels. Come later that following year, ''WesternAnimation/TheLittleMermaidIIIArielsBeginning'' turned out to be the last produced of these sequels (that isn't ''Franchise/DisneyFairies'' or an official sequel like ''WesternAnimation/ToyStory3'' onward). Does that mean Stewie succeeded in taking over the world in this timeline?

* ''HilariousInHindsight/UltimateSpiderMan2012''

* ''WesternAnimation/ThePowerpuffGirls1998'':

* An article released before ''WesternAnimation/BigHero6'' compared Wasabi to Cyborg from ''WesternAnimation/TeenTitans2003''. Cut three years to [[WesternAnimation/BigHero6TheSeries the cartoon]], and he's voiced by Creator/KharyPayton, who's often considered the definitive voice for him.

** 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.

* In the early episode “Lethal Weapons”, Lois practices a martial art called “Tae-Jitsu”. It’s more amusing nowadays, when ''Manga/{{Naruto}}'' is pretty well-known: there, the style of martial art is called “taijutsu”.
* "April in Quahog" has a cutaway gag where Mayor West punches the Orion constellation [[ForTheEvulz for no reason]]. It then turns into the Creator/OrionPictures logo, causing him to say "That's right. All you are is a failed production company." Come 2013 and Orion began it's rise from the ashes with the relaunch of Orion Television and then in 2014 the main Orion movie label was relaunched.
* In a earlier episode of the series, one of Meg's friends mentions that Brian looks like Creator/BenAffleck. The ''WesternAnimation/SuperFriends'' parody has Brian play the role of Batman. Guess which actor later played Batman?

* ''WesternAnimation/JusticeLeagueDark'' sees Creator/JeremyDavies reprise his ''Series/{{Constantine}}'' role of Ritchie Simpson, who serves as a patsy for Dr. Destiny ([[AdaptationNameChange albeit without the "Doctor" in the name]]). In the Series/{{Arrowverse}} crossover ''Series/Elseworlds2018'', he played Dr. Destiny himself [[[ComicBookMoviesDontUseCodenames albeit only called John Dee]][[AdaptationNameChange (gan)]]].

** "The Laughing Cats" sees Batgirl state she isn't a cat-person. Her actress, Creator/DanielleJudovits, would appear in ''WesternAnimation/WolverineAndTheXMen2009'' as a character nicknamed ComicBook/{{Kitty|Pryde}}.

* Creator/LaurenFaust created ''WesternAnimation/SuperBestFriendsForever'', which focuses on female DC heroes, but it was turned. Cut to 2019, and she's in charge of the television version of ''WesternAnimation/DCSuperHeroGirls'', a franchise that also focuses on female DC heroes. SpiritualSuccessor much?

* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' season 2 finale "Win, Lose and Kaboom!" the episode parodies hit reality television show ''Series/{{Survivor}}''. During that spoof Bolbi voted himself off and is sent to the Cell of Indignity [[spoiler:(in there he spent the rest of the game being pampered and waited on by two beautiful alien women providing him food from home)]]. Two years later on ''[[Characters/SurvivorMicronesia Survivor Micronesia]]'', contestant Cirie Fields asked contestant Erik Reichenbach [[spoiler:to give her the immunity necklace he won in the Immunity Challenge thus voting himself out of the game]]. On ''[[Characters/SurvivorHeroesVsVillains Survivor Heroes vs Villains]]'', Tyson Apostol [[spoiler:switched his vote from Russell Hantz to Parvati Shallow at the last minute in the tribal council. Hantz used an immunity idol for Shallow thus resulting in Apostol being voted off instead of sticking to the split vote plan]]. In the season ''[[Characters/SurvivorGameChangers Survivor Game Changers]]'', during the tribe switch contestant Debbie Wanner became the only castaway without a buff and is sent to Exile Island. [[spoiler:When Debbie got there the "island" was a yacht which was loaded with food from home and advice from former contestant John Cochran.]] On another CBS show ''[[Characters/BigBrother19 Big Brother 19]]'' there was a memory competition for the POV. Each houseguest had to get a question right in order to advance to the next round, and if a houseguest got a question wrong they would have to complete a challenge. [[spoiler: One of the challenges was an eating challenge which houseguests Elena Davies, Josh Martinez and Matthew Clines did after they got a specific question wrong. They were forced to eat something gross, which is the exact same challenge Carl Wheezer did in "Win, Lose and Kaboom!"]]

** In "[[Recap/BobsBurgersS8E21SomethingOldSomethingNewSomethingBobCatersForYou Something Old, Something New, Something Bob Caters for You]]", the wedding guests receive boxes that, when opened, were supposed to release butterflies. However, all the butterflies were revealed to be dead, and the crowd threw them into the air to pretend they were flying. One month later, [[https://decider.com/2018/06/29/bobs-burgers-predicted-drag-race-finale-butterflies/ something very similar happened]] during Asia O’Hara’s performance on the 10th season finale of ''Series/RuPaulsDragRace''.

* The elections in the ''WesternAnimation/LittlestPetShop2012'' episode "[[Recap/LittlestPetShop2012S2E18InsideJob Inside Job]]" (which aired in 2014) echoes some opinions about the 2016 U.S. presidential election, with one candidate focused on spending money and making verbal jabs while the other one initially plays nice but decides to play dirty later on. The school collectively settling on a third student mirrors some sentiments of voting for a third-party candidate.

* ''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]]?

* The 1990s ''WesternAnimation/XMenTheAnimatedSeries'' 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.

** In ''WesternAnimation/XMenEvolution'' when the Brotherhood is first introduced to [[ComicBook/ScarletWitch Wanda]], Lance sarcastically asks whether she's Pietro's old girlfriend, when in fact she is his sister. Later, in the [[ComicBook/TheUltimates Ultimate Avengers]] universe, they would be [[BrotherSisterIncest boyfriend and girlfriend, as well as brother and sister]]!

* From the ''WesternAnimation/BettyBoop'' cartoon ''WesternAnimation/MinnieTheMoocher'': The titular song contains a line about Minnie meeting the king of Sweden. The character singing the song is a walrus. LetsPlay/{{Robbaz}}, a Swedish Website/{{YouTube}}r who started his channel in 2006, jokingly calls himself "king of Sweden" and associates himself with walruses.

** To anyone who uses Website/{{Tumblr}} or Website/LiveJournal, that entire scene will either make you roll on the floor laughing, or cringe uncomfortably for the same reason: You've seen that conversation take place, maybe even word for word.

* Around the time when ''WesternAnimation/MollyOfDenali'' first premiered, Website/GoAnimate users [[InsaneTrollLogic claimed that the show was a ripoff]] of ''WesternAnimation/WildKratts''. Three years later, the Kratt brothers themselves would guest-star on ''Molly of Denali''.
