Cartman: Hey! Have you guys ever seen this trick? When someone's sleeping, you can take a glass of warm water, and you put their hand in it - (puts Butters' hand in water)
Stan: Yeah, and then what?
Cartman: And then, you pee on them. (pees on Butters)
Kyle: No, dude, you're supposed to put their hand in warm water and it makes them pee!
Cartman: Oh, really? Oh well. (continues peeing)
