History HarsherInHindsight / WesternAnimation

* An in-universe example in ''{{Futurama}}'': when the cast are de-aged to teenagers in the episode "Teenage Mutant Leela's Hurdles", teenage Amy is rather pudgy. Several seasons later, in "The Prisoner of Benda", it's revealed that young Amy's overweight was caused by an eating disorder.

* ''The Koos is Loose'' episode of ''WesternAnimation/DextersLaboratory'' is hard to watch after Dom [=DeLuise=]'s death now, what with the episode ending with Dexter imagining Koos away and Koos' line "Goodbye Dee Dee, goodbye Dexter. You'll never see me again..."

* ''The Koos is Loose'' episode of ''DextersLaboratory'' is hard to watch after Dom [=DeLuise=]'s death now, what with the episode ending with Dexter imagining Koos away and Koos' line "Goodbye Dee Dee, goodbye Dexter. You'll never see me again..."

* ''BlitzWolf'', an MGM WartimeCartoon, features the Three Little Pigs blowing up Tokyo after an [[OverlyLongGag overly-long gun barrel gag]] [[hottip:*:The edited version on CartoonNetwork makes it look like the pigs were aiming their gun at the Hitler Wolf's trench]]. This was ''three years'' before two Japanese cities (Hiroshima and Nagasaki) really would be blown to pieces -- [[ILoveNuclearPower with atomic weapons]], no less.

* In the ''MyLittlePonyFriendshipIsMagic'' two-parter "Canterlot Wedding," the need for increased security at the wedding seems a bit more eerie in light of the recent issues with insufficient security at the London 2012 Olympics.

* ''LooneyTunes'': in the cartoon "Often an Orphan", Charlie Dog's FreakOut includes the line "Look! It's the towers! THEY'RE FALLING!!", though, considering that the World Trade Center towers weren't erected until the late 1960s into the 1970s, this example of HarsherInHindsight is more of a FunnyAneurysmMoment due to an oversensitive populace reacting to anything that has to do with buildings collapsing.

** In "$pringfield (Or, How I Learned to Stop Worrying and Love Legalized Gambling)," one of the many failures at Burns' casino is that Siegfried & Roy expies Gunther and Ernst are mauled by their own tiger while entertaining. Ten years later, it happened in real life to Roy Horn. The writers mentioned in the DVD commentary that the incident was bound to happen sooner or later and they were amazed when it did.
** From season seven's "The Day The Laughter Died" when Bart and Lisa were watching a ''SchoolhouseRock'' parody (or as Lisa puts it, a "...campy 70s throwback that appeals to Generation X-ers"): "[[TheVietnamWar We need another Vietnam]] [[TheWarOnTerror to thin out their ranks a little.]]"

* The scene in "Lisa's Date with Density" where Milhouse ends up getting wheeled to the hospital after Nelson beat up Milhouse over a love note that supposedly was from him stops being funny thanks to the recent rash of gay, lesbian, bisexual and transsexual teens getting physically and emotionally abused in school (some of which have taken their own lives because of it).

** "201" reveals that [[spoiler: Scott Tenorman and Cartman were brothers, due to having the exact same father, which meant that Cartman killed his own father. Cartman doesn't seem too concerned about having commited patricide, though.]]

* ''TheCritic'' has two:

* ''LooneyTunes'': in the cartoon "Often an Orphan", Charlie Dog's FreakOut includes the line "Look! It's the towers! THEY'RE FALLING!!"

*** The scene in "Lisa's Date with Density" where Milhouse ends up getting wheeled to the hospital after Nelson beat up Milhouse over a love note that supposedly was from him stops being funny thanks to the recent rash of gay, lesbian, bisexual and transsexual teens getting physically and emotionally abused in school (some of which have taken their own lives because of it).

** The rise of bullying-related suicides (especially Phoebe Prince) makes the infamous "The Boys Of Bummer" even harder to watch.

** In "Jungle Love", Lois baits Chris to the high-school kids who want to paddle him. At first this may seem like a strange OutOfCharacterMoment, but due to her [[BitchInSheepsClothing more recent]] [[{{Flanderization}} characterization]] this is just a walk in the park for her.
* In Disney's ''{{Disney/Pinocchio}}'', the Coachman takes unsuspecting boys to [[AmusementParkOfDoom Pleasure Island]], where he turns them into donkeys and sells them to slavery. ''Then along came Kony...''

* The 2011 remake of ''WesternAnimation/{{Arthur}}'' had RussellBrand playing a funny alcoholic (just like Dudley Moore in the original). Three and a half months later, his friend AmyWinehouse died trying to kick an alcohol addiction. Brand (who himself was a drug, alcohol, and sex addict back when he was only famous in England) is now trying to get Hollywood to help celebrities fight their addictions.

* ''Disney/OneHundredAndOneDalmatians: The Series'', which was released in 1997, had an episode "Alive N Chicken" where Spot the chicken tries various methods to fly. The episode was banned because of the 9/11 attacks, especially the part when Spot flew into the Dog Chow Tower. It's because of this that the episode was banned in reruns.
* In a late first season episode of ''AvatarTheLastAirbender'', CoolOldGuy Iroh declines an offer to have his fortune told, saying that, "At my age there is really only one big surprise left, and I'd just as soon leave it a mystery." Roughly a year later, just after finishing recording his lines for the second season, his voice actor (Makoto Iwamatsu, best known by his stage name "Mako") died of esophageal cancer at 72.

** Try "Bart of Darkness" where Bart witnesses Flanders scream bloody murder over killing something, the entire episode it is implied to be Maude until the last second, with "She's with God" meaning Bible Camp. Now try watching that episode after watching the one where Maude dies.
** In "Bart The General", Bart has a nightmare where he's killed by Nelson and Nelson walks up to Bart's corpse in a casket saying "Here's one for the road" followed by [[KickTheDog punching his corpse]]. Now try watching that when you find out that the [[TeensAreMonsters bullies who]] [[DrivenToSuicide drove Phoebe Prince to suicide]] [[MoralEventHorizon laughed at her casket]].
*** Speaking of Phoebe Prince, try watching "The Boys Of Bummer" (which already left a horrible taste in the collective mouths of whatever fans remain of the show due to how cruel the townspeople treated Bart over his botched play during a Little League game) with her in mind. If it hasn't already, it '''''will''''' make you want to send death threats to the writers.

** In "$pringfield (Or, How I Learned to Stop Worrying and Love Legalized Gambling)," one of the many failures at Burns' casino is that Siegfried & Roy are mauled by their own tiger while entertaining. Ten years later, it happened in real life to Roy Horn. The writers mentioned in the DVD commentary that the incident was bound to happen sooner or later and they were amazed when it did.

** From "The City of New York vs. Homer Simpson" (which is already plagued with being dated and depressing following the 9/11 attacks): "They put all the jerks in Tower One!" [[OldShame On the DVD commentary, the writers said they felt really bad about that line after 9/11.]]
** In the season one episode "Krusty Gets Busted," Krusty the Clown has a heart attack from grilling pork products during an episode of ''The Krusty The Clown Show'' (which is a clue in clearing Krusty of the robbery charge). In season three's "Like Father, Like Clown," Krusty is revealed to be Jewish.
** With all the concern over kids in school getting bullied (particularly ones who recognize that they are homosexual) these days, the flashback in season 12's "Bye Bye Nerdie" where Homer punches Smithers (wearing a pink shirt and shorts to school) in the stomach while singing "Kung Fu Fighting" (with Barney on the recorder providing instrumentals) would raise a lot of cries of "DudeNotFunny".

* In the ''very first episode'' of EdEddNEddy, the Eds falsely accuse Jonny of stealing everybody's stuff and as punishment is sent rolling down a hill in a tire. After it turns out he didn't, Edd asks Eddy if they should feel sorry for Jonny's predicament. Eddy nonchalantly replies "You know what they say. [[MiseryBuildsCharacter A little childhood trauma builds character.]]" Guess Eddy really meant that, given [[spoiler:how the series finale movie revealed that Eddy's brother has physically abused him for as long as they've been together]].

* In Disney's ''{{Disney/Pinocchio}}'', the Coachman takes unsuspecting boys to [[AmusementParkOfDoom Pleasure Island]], where he turns them into donkeys and sells them to slavery. ''Then along came Kony...''

** [Mixed with SeriesContinuityError]: In the season one episode "Krusty Gets Busted," Krusty the Clown has a heart attack from grilling pork products during an episode of ''The Krusty The Clown Show'' (which is a clue in clearing Krusty of the robbery charge). In season three's "Like Father, Like Clown," Krusty is revealed to be Jewish.

** "201" reaveals that [[spoiler: Scott Tenorman and Cartman were brothers, due to having the exact same father, which meant that Cartman killed his own father. Cartman doesn't seem too concerned about having commited patricide, though.]]

* The opening of ''Disney/OliverAndCompany'' shows shots of the World Trade Center, followed by a box of orphaned kittens. The orphaned kittens were probably sad enough before 9/11, but now, this troper found that scene to be gut-wrenching, because of the connection one can make between the two towers and the orphans.

** In "Bart The General", Bart has a nightmare where he's killed by Nelson and Nelson walks up to Bart's corpse in a casket saying "Here's one for the road" followed by [[KickTheDog punching his corpse]]. Now try watching that when you find out that the [[CompleteMonster bullies who]] [[DrivenToSuicide drove Phoebe Prince to suicide]] [[MoralEventHorizon laughed at her casket]].

** Speaking of ''The Simpsons'', it's a little unsettling watching the musical version of ''AStreetcarNamedDesire'' where they call New Orleans "The Sodom and Gomorrah of the Mississip'" after {{God}} agreed with them.

** In "$pringfield (Or, How I Learned to Stop Worrying and Love Legalized Gambling)," one of the many failures at Burns' casino is that Siegfried & Roy are mauled by their own tiger while entertaining. Ten years later, it happened in real life to Roy Horn. The writers mentioned in the DVD commentary that the incident was bound to happen sooner or later.

** In a first season episode Krusty the Clown is shown having a heart attack on the air while grilling pork products. Two seasons later Krusty is revealed to be Jewish.

* In ''TheIncredibles'', Violet worried that her parents lives were in danger, and then started worrying about their marriage. Her brother Dash laughed at the idea of villains wanting to ruin the marriages of superheroes. [[OneMoreDay Three years later...]]

** The episode "Sherman, Woman and Child," (aired in March 1995) had a scene in which Jay's chain smoking make-up artist Doris Grossman attempted to make a smoke ring bunny but it ended up turning into a shape with a demon-like appearance which told her [[http://www.youtube.com/watch?v=vaMBKDA-vzw "Doris...Tick! Tock!"]] Seven months after it aired, her voice actress Doris Grau died from emphysema. Also counts as a FunnyAneurysmMoment.

* In-universe example - In the ''SouthPark'' episode "Cartman Joins NAMBLA", the boys are playing some Life-esque board game. Cartman gives Kyle AIDS in the game. The other characters are horrified by this. In the episode "Tonsil Trouble" (which aired 8 years later), Cartman literally infects Kyle with AIDS.

* In the ''very first episode'' of EdEddNEddy, the Eds falsely accuse Jonny of stealing everybody's stuff and as punishment is sent rolling down a hill in a tire. After it turns out he didn't, Edd asks Eddy if they should feel sorry for Jonny's predicament. Eddy nonchalantly replies "You know whta they say. [[MiseryBuildsCharacter A little childhood trauma builds character.]]" Guess Eddy really meant that, given [[spoiler:how the series finale movie revealed that Eddy's brother has physically abused him for as long as they've been together]].
