There was this scene in The Fairly Oddparents in which Timmy, Cosmo, and Wanda went to visit Anti-Cosmo:
Anti-Cosmo: *comes out of the shadows in his glass-walled prison* Hello Clarice.
Wanda: Who's Clarice?
Anti-Cosmo: Whoops. Sorry, I can't see anything without my monocle on.
In Toy Story, there is the following:
Mr. Potato Head: Look, Hamm, I'm Picasso.
Hamm: Gee, I don't get it.
Mr. Potato Head: You uncultured swine!
Batman: The animated seris:
Pshcopathic (we're talking genuialy crazy people here) villians
The Joker abuseing Harley Quinn.
Harley throwing herslef in lingre before the Joker
The obvious lesbian undertones for Poison Ivy and Harley Quinn
The death of a main charachter (Batgirl)
Two Face hearing voices.
General dark tone. :D
Avatar is very good at this game.
"Don't worry Sokka, where we're going, you won't need any pants!"
"So it looks like I'm gonna be in town for awhile. I'm thinking maybe we could do an activity together?"
"Do an activity?"
"I have a surprise for everyone!"
"I KNEW IT! You did have a secret thing with Haru!"
There's a lot.
Spongebob and Rugrats have a few.
One I can think of from Spongebob,even though I could be very wrong.But in The Camping Episode,when Squidward keeps coming in and out of the tent,I swear Spongebob and Patrick were looking at porno magazines.
Hope I helped.
