Kelso

I'm sorry. Look, I've been screwed by Darwinism... never needed to evolve listening skills 'cause my looks are so highly developed.

Donna

Um, that's not how evolution works.

Kelso

Yeah, sure it is. Look, say I had to catch my own food, right? But I only ate really fast animals? My feet would eventually evolve into rockets.

Hyde

Man, it's amazing your brain doesn't evolve into pudding.
