History ExplainExplainOhCrap / WesternAnimation

** In "The Big Zipp Attack", when the Turtles fire encounter the {{Metal Munch|er}}ing Zipp, they see it double after taking a bite out of Donatello's latest invention before the pair escape to the surface. Upon hearing that Donatello's invention was made of copper, Leonardo deduces that the Zipps will double anytime they eat copper.

** In "The Halloween Door", when a horde of demons escape from the Netherworld and terrorize New York in celebration, Winston realizes they may want a few other friends join the fun:

-->'''Homer:''' ''(Singing)'' Simpson, Homer Simpson / He's the greatest guy in history / From the town of Springfield / He's about to hit a chestnut tree ''(ScreamsLikeALittleGirl, and then he does)''

** In "Something Fishy This Way Comes", Jake is on the hunt for an escaped Kelpie, a sea creature that drains the life force and absorbs the powers and appearance of whatever it bites. Jake initially suspects that the Kelpie is his school principal Ms. Derceto, who has recently started dating his grandfather. When he and his friends break into her office at school, they find rusted old chains covered in seaweed, which only fuels his suspicions. After he finally confronts her, he discovers that [[spoiler:she's actually a mermaid detective who's also tracking down the Kelpie]]. After the misunderstanding is cleared up, Jake soon realizes they've got another problem; the ''real'' Kelpie is still on the loose, which means Lao Shi is in danger.

** In "Joker's Millions", The Joker receives an UnexpectedInheritance in cash from a rival gangster. After going on a spending-binge, he goes through the vault to pay inheritance tax when one of his minions notices something off about the cash. Joker takes a closer look and sees a different face on the currency.

* In the ''WesternAnimation/AmericanDragonJakeLong'' episode "Hong Kong Knight", Fu Dog tells Jake the story of how his grandfather Lao Shi met Fu and Counselor Chang, and how his encounter with the Dark Dragon made him the no-nonsense dragon he is today. While thinking over the story, Jake remembers how it was Chang that told Lao Shi and Fu to investigate the cargo hold of a ship, which was where the Dark Dragon was. Jake suggests that it's likely Chang intended Lao Shi to run into the Dark Dragon. And if Chang was working with the Dark Dragon then, then she might be working for him now... [[OhCrap while his grandfather is alone on business with her]].

* ''WesternAnimation/{{Rugrats}}'':

** In "[[Recap/SpongeBobSquarePantsS2E20SquidOnStrikeSandySpongeBobAndTheWorm Sandy, SpongeBob, and the Worm]]", we get an interesting form of this trope where the realization hits ''early'' in the explanation, but it takes Sandy saying it out loud for before the actual implications of the realization hits her.

-->'''Fred:''' ''(Jovially as he looks at the mask his boss was wearing)'' Sure! I talked to you! We were at the refreshment bar and I was saying...Oh, boy, what I was saying!\\

** "Groundpiglet Day": Rabbit becomes convinced that it's Groundhog Day, due to his calendar pages blowing away, and hires Piglet to be a groundhog.

** Another Sylvester example: in the cartoon "WesternAnimation/MuzzleTough", Sylvester tries to get past a guard dog by [[FullBodyDisguise disguising himself]] as a [[DisguisedInDrag sexy female dog]], only to [[GoneHorriblyRight get scooped up by a dogcatcher]] before he can get anywhere with it. As the catcher's van drives off, Sylvester yells as them from the back of the truck:
