Animaniacs, Season 1

Ms. Flamiel:
Stop that! STOP THAT! SIT AT YOUR DESKS THIS INSTANT!

[The Warners jump into their seats & sit quietly. Ms. Flamiel pulls a red marker pen out of her cleavage]

Yakko:
Ooh, what else ya got in there?

Ms. Flamiel:
Why, you little...! F! [Writes an F on Yakko's forehead]

Dot:
Hey, you can't do that to him!

Ms. Flamiel:
F! [writes an F on Dot's forehead, causing her to cry; Wakko buries his head in his arms, laughing; glares at him, then writes an F on his hat with a black marker] F!

[Wakko stops laughing then stares at the F, he then gets very livid and starts to shake his head]

Yakko:
Uh, oh. Now you've gone and hurt his feelings.

Dot:
I'd apologize if I were you.

Ms. Flamiel:
I will NOT! You're horrid, naughty children!

[Growling, Wakko grabs his desk and shakes, steam shooting out of his nose. Ms. Flamiel starts to look worried. Finally, the top of Wakko's hat blows up like a volcano. Ms. Flamiel covers her eyes as Wakko's head explodes offscreen]
