Here is my fave, from "Beavis & Butt-Head meat god". I don't remember exactly, but it goes something like dat:
"God" (talking with himself) : And I said to Moses: "Take your people to
the promised land", and Moses said:
"Huh-huh, huh-huh, huh-huh, huh-huh..."The second best one is this (while watching Culture Club's "Karma Chameleon):
Butt-Head: Is it... the future? Beavis: Yeah, yeah, this sucks! Change it, Butt-Head! Butt-Head: I'm pretty cool, Beavis, but I can't change the future!
And also from the first Rolling Stone interview (while talking about allowed and forbidden words):
Beavis: We can say "butthole"! Butthole! Butthole! Butthole! Butt-Head: Shut up, Beavis! MTV will fire you! Beavis: Fire! Fire! Fire!
