Ross: I have a bone to pick with you.
Rachel: Uh-oh.
Ross: Yes. Ben learned a little trick.
Rachel: Oh, yeah, did he pull the old?
Ross: That's right, that's right. Saran wrap on the toilet seat so the pee goes everywhere.
Rachel: Oh, that.
Ross: Yeah, that. You know I hate practical jokes. They're mean and they're stupid and I don't want my son learning them.
Rachel: Come on. Saran wrap on the toilet seat? You don't think that's just a little funny?
Ross: I was barefoot.
Rachel: Oh.
Ross: Now, tell me, the toilet thing is the only thing you taught him, right?
Rachel: Yes.
