Quote from Joey in The One with Phoebe's Rats
Ross: Hey, listen, Joey. About Molly, I would really prefer if you didn't go after her. Joey: Why not? Ross: Because it took us months to find a good nanny. And I wouldn't want anything to, you know, drive her away. Joey: So what? You think I'm just gonna sleep with her and never call her again, and things are gonna get uncomfortable? Yeah, that sounds about right.
