Caveman 1: Hey check this thing out, it's shaped like a circle and it moves around easier than big rocks. Caveman 2: What are you gonna use it for? Caveman 1: I don't know, but I'm gonna call it a wheel, just remember I invented the wheel. Caveman 2: It's really not that great, what are you gonna do with it? Caveman 1: I don't know dude, wheel it around I guess, shut up! You're always nay-saying! You did this when I invented the plate too! Caveman 2: Well the wheel is the same thing as a plate, the only difference is it has a hole in the middle. Caveman 1: Yeah, you're right, it's really not that great is it? Caveman 2 : No, not really Caveman 1: Wanna go kill a Woolly Mammoth? Caveman 2: F*ck. Yes.
