Monica: So how do you guys like living together so far?
Ross: It's been good.
Rachel: Yeah. But Ross is more uptight about crumbs than you are.
Ross: There was a drumstick in the couch.
Monica: And I am not uptight about crumbs. It's just that, you know, crumbs attract mice and mice leave droppings and that's how the plague started. So, if you wanna relive that again...
Rachel: Mice didn't start the plague, rats did. Rattus norvegicus to be exact. ... Oh, good God, Ross. Nick at Nite, once in a while.
