History ButForMeItWasTuesday / WesternAnimation

* ''WesternAnimation/TheVentureBrothers'', Brock Sampson, with various characters from his past: "Do I know you?"
** [[SubvertedTrope Subverted]] when he meets 21 again in Season 3. He does recognize him, but decides to mess with him.

'''Blight:''' ''(irritated)'' Do you have the ''slightest'' idea how ''little'' that narrows it down?\\

* In ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'', Deadman, possessing Wonder Woman, beats the crap out of Devil Ray, telling him that he killed his mentor and friend.

-->'''Sheen:''' So?! What if I don't?! A lot's happened since then!"

** "[[Recap/TheSimpsonsS6E25WhoShotMrBurns Who Shot Mr. Burns? Part One]]" took this to extremes, with Homer breaking into Mr. Burns' office, spray-painting "I AM HOMER SIMPSON" along his walls in huge neon green letters, and Mr. Burns' response is, "Who the devil are you?" This drove Homer mad.

** "[[Recap/TheSimpsonsWhoShotMrBurnsS6E25 Who Shot Mr. Burns? Part One]]" took this to extremes, with Homer breaking into Mr. Burns' office, spray-painting "I AM HOMER SIMPSON" along his walls in huge neon green letters, and Mr. Burns' response is, "Who the devil are you?" This drove Homer mad.

** The "[[Recap/TheSimpsonsWhoShotMrBurns Who Shot Mr. Burns?]]" two-parter took this to extremes, with Homer breaking into Mr. Burns' office, spraypainting I AM HOMER SIMPSON along his walls in huge neon green letters, and Mr. Burns' response is, "Who the devil are you?" This drove Homer mad.

** The first Hunter was Gillecomgain, who was just some farm kid who went to investigate a noise coming from the stable, where he surprised Demona, who was homeless, hungry, and stealing food. In a reaction that was part instinct and part petty malice, Demona casually [[ScarsAreForever mangled his face]] before fleeing. Gillecomgain responded to ''that'' by becoming [[FromNobodyToNightmare one of the most skilled and dangerous warriors/assassins in Scotland]], and, in between [[ProfessionalKiller carrying out assassinations]] for the paranoid and power hungry King Duncan, went on a personal crusade to try to destroy any gargoyles he could find and especially to relentlessly hunt down Demona. Several decades and many battles later, she finally overpowers Gillecomgain, unmasks him, and is momentarily taken aback when she sees his face. He draws her attention to his scars and asks if she now knows why he hunted her for so long... only to be shocked and infuriated when she flatly replies "No", having obviously never given their encounter a second thought and most likely having forgotten it the moment after she left that stable. After Gillecomgain is killed, Duncan takes up the mask and the position of Hunter, and after ''he's'' gone, Duncan's descendants carry on the hunt for Demona for the next thousand years, and she ''still'' doesn't know why (not that she would care anyway). In a deleted scene from "Hunter's Moon: Part Two", the leader of the latest generation of Hunters confesses to Elisa that no one in his family remembers how or why the hunt began, either.

* In ''WesternAnimation/SupermanTheAnimatedSeries'', Superman finally ends up fighting {{ComicBook/Darkseid}} and gives him an AndThisIsFor punch for Dan Turpin, the man he killed during the Apokolips invasion. Darkseid has no idea who he is talking about and merely exclaims "Had I known one human's death would pain you so, I would have killed more."

** Also, in ''WesternAnimation/Ben10Omniverse'', with [[RememberTheNewGuy Billy Billions]], a former classmate who was [[GreenEyedMonster envious of Ben when they were eleven years old]] and [[DisproportionateRetribution tried to zap Ben in Dimension 12]], resulting in [[HoistByHisOwnPetard him ending up trapped in that dimension after he tried to shoot at Diamondhead]]. Turns out Ben not only doesn't remember him, he ''[[ExaggeratedTrope wasn't even aware of his existence]]''.

Turns out Ben not only doesn't remember him, he ''[[ExaggeratedTrope wasn't even aware of his existence]]''.

* ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'': In the episode "The League of Villains", Jimmy has created a way to restore his and his friends superpowers from a previous episode, "The N-Men", and of course all of his friends want their powers back for their own purposes. But of course Jimmy refuses, asking them if they remember how out of control they all went last time and they all shamefully say yes... Except for Sheen, who everyone looks at. His response?
---> '''Sheen:''' So?! What if I don't?! A lot's happened since then!"

'''Bart:''' I'm Bart Simpson. [[Recap/TheSimpsonsS1E12KrustyGetsBusted I saved you from jail]]. ''(Krusty mutters non-recognition.)'' [[Recap/TheSimpsonsS3E6LikeFatherLikeClown I reunited you with your estranged father]]. ''(Continued non-recognition.)'' [[Recap/TheSimpsonsS4E22KrustyGetsKancelled I saved your career, man! Remember your comeback special?]]

'''Mr. Burns''': Simpson, eh?

--->'''Bart''': Did you kill my principal?
--->'''Fat Tony''': Uh, Chinese guy with a moustache?

--->'''Krusty:''' Good job, kid. What's your name?
--->'''Bart:''' I'm Bart Simpson. [[Recap/TheSimpsonsS1E12KrustyGetsBusted I saved you from jail]]. ''(Krusty mutters non-recognition.)'' [[Recap/TheSimpsonsS3E6LikeFatherLikeClown I reunited you with your estranged father]]. ''(Continued non-recognition.)'' [[Recap/TheSimpsonsS4E22KrustyGetsKancelled I saved your career, man! Remember your comeback special?]]
--->'''Krusty:''' Yeah, well, WhatHaveYouDoneForMeLately
--->'''Bart:''' [[RhetoricalQuestionBlunder I got you that danish!]]
--->'''Krusty:''' And I'll never forget it.

* Played with in the 1990s ''WesternAnimation/XMen'' series before Quicksilver and Scarlet Witch [[LukeIAmYourFather find out the real truth]]:

** The "[[Recap/TheSimpsonsWhoShotMrBurns Who Shot Mr. Burns?]]" two-parter took this to extremes, with Homer breaking into Mr. Burns' office, spraypainting I AM HOMER SIMPSON along his walls in huge neon green letters, and Mr. Burns' response is, "Who the devil are you?" This pushes Homer's BerserkButton.

** Also, in ''WesternAnimation/Ben10Omniverse'', with [[RememberTheNewGuy Billy Billion]], a former classmate who was [[GreenEyedMonster envious of Ben when they were eleven years old]] and [[DisproportionateRetribution tried to zap Ben in Dimension 12]], resulting in [[HoistByHisOwnPetard him ending up trapped in that dimension after he tried to shoot at Diamondhead]]. Turns out Ben not only doesn't remember him, he ''[[UpToEleven wasn't even aware of his existence]]''.

* ''WesternAnimation/Invincible2021'': Referenced when Mark, who is [[PubertySuperpower new to Superheroics]], awkwardly returns home without his father, looking significant worse for wear. His mother is concerned at first, but upon hearing that Omni-man went into another dimension to fight back some invading aliens, she relaxes entirely, noting that he'll probably be late for dinner.
-->'''Debbie:''' I was worried before because I've never seen your father so badly hurt, but taking on aliens in another dimension? That's just Tuesday.
* On ''WesternAnimation/JimmyTwoShoes'', Heloise is prone to this.
** In "The Mysterious Mr. Ten", when Jimmy confronts her about putting a curse on [[MisunderstoodLonerWithAHeartOfGold Mr. Ten]], she tells him that she needs more information and shows Jimmy a long list of people she's cursed.
** In "Rear Pickle", Jimmy fears that Beezy has been murdered by their new neighbor and panics when he sees her throwing a large bodybag into a hole, leading to this exchange.
-->'''Jimmy:''' She's burying something!\\
'''Heloise:''' (''bored tone'') Who hasn't?

* ''WesternAnimation/SamuraiJack'': Aku has shades of this, best shown in the episode "Jack vs. Aku." While Jack considers it his life's mission to destroy Aku and treats their battle with the utmost seriousness, Aku considers their conflict to be nothing more than just some kind of game, one that's [[StatusQuoIsGod gotten a bit long and tedious for him]]. However, come Season 5, Aku has gone from finding it tedious to nightmarish, having been reduced to a NervousWreck after exhausting every single method he possibly could trying to kill Jack, including [[VictoryByEndurance letting time handle things for him]], and hiding in his castle so Jack can't kill him.
** [[spoiler:Aku is ultimately surprised at the existence of Ashi because he was doing little more than jokingly humoring the Cult of Aku with a gift, when he paid them a visit. He ''really'' has to think back to remember doing it, too. Before that, he didn't even recognize the Scotsman as being one of his main enemies, even when he clearly had the means to harm him. All this chalks up to Aku having a rather poor memory]].

** This exchange in "[[Recap/TheSimpsonsS13E6SheOfLittleFaith She of Little Faith]]" after Homer [[ItMakesSenseInContext accidentally destroys the town church with a homemade rocket.]]
--->'''Marge''': This is the worst thing you've ever done!
--->'''Homer''': You say that so much it's lost all meaning.

* On ''WesternAnimation/JimmyTwoShoes'', Jimmy finds out that [[MisunderstoodLonerWithAHeartOfGold Mr. Ten]] had been cursed by Heloise, he goes and confronts her about this. Being [[AxCrazy Heloise]], she needs more information, showing Jimmy a long list of people she's cursed.

** [[TheDragon Princess Azula]] shows herself to be this type of villain when her {{plan}} against her brother begins to take shape in Season 3. You can almost see her going through the exhaustive list in her head of My-Diabolical-Plots-Against-Zuko.

*** That said, Macbeth does ''remember'' Canmore, he just doesn't recognize him. It's been over fifteen years since they last met, and Canmore was [[JustAKid just a young boy]] back then instead of a grown, large, vengeance driven man. The moment Canmore ''says'' who he is instead of waiting for Macbeth to recognize him on sight, he gets a different reaction.

** The first Hunter was Gillecomgain, who was just some farm kid when Demona casually mangled his face after he caught her stealing food. He made a mask to highlight the scars and began hunting her relentlessly. Several decades later, she finally overpowers him and unmasks him before dealing the finishing blow. He draws her attention to his scars and asks if she now understood why he had hunted her for so long...only to be infuriated when she flatly replies, "No." After he is killed, Duncan takes up the mask and position of Hunter. Duncan's descendants began a thousand-year blood hunt for Demona, and she ''still'' doesn't know why (not that she would care anyway). In a deleted scene from "Hunter's Moon: Part Two", the leader of the latest generation of Hunters confesses to Elisa that no one in his family remembers how or why the hunt began, either.

*** Of course, he does ''remember'' Canmore, he just doesn't recognize him. It's been over fifteen years since they last met, after all, and Canmore was just a young boy back then.

* ''WesternAnimation/Invincible2021'': Referenced when Mark, who is [[PubertySuperpower new to Superheroics]], awkwardly returns home to tell his Mom thas his Dad, (Omni-man went into another dimension to fight back some invading aliens. She relaxes enitrely upon hearing this is all that happend, noting that he'll probably be late for dinner.
-->'''Debbie:''' I was worried before because I've never seen your father so badly hurt, but taking on aliens in another dimenson? That's just Tuesday.

** Note that Magneto may not remember the many who "have fallen in his path", but he '''does''' remember Magda. In fact, he was paying a visit to her grave right there, before being ambushed. They really ''should'' have been more specific.

** Played nearly straight when Katara finally tracks down the man who murdered her mother when she was a child. At first, he has no idea what she's talking about, but recalls it clearly after Katara jogs his memory.
