Mr. Candy: Who can tell me what I'm holding in my hand? (holding up a candy bar)
Butt-head: Uh... your nads?
Beavis: Yeah.
Mr. Candy: No, my right hand.

Mr. Buzzcut: All right, losers. Remember, you are competing against other classes. And I'll be damned if my class is gonna lose!!!

(Beavis and Butt-head try to sell a candy bar to Mr. Anderson)
Mr. Anderson: Yeah?
Butt-head: Uh... our school's making us sell candy.
Beavis: Yeah. We're losers.
Mr. Anderson: What in the hell kind of sales approach is that? You boys couldn't sell a dollar for fifty cents.

If Beavis really ate an entire box of chocolate bars, he should have morphed into his alter-ego, the Great Cornholio, as Cornholio emerges whenever Beavis consumes too much sugar or caffeine.
