Quote from Rachel in The One with Ross's Grant
Phoebe: Oh, and I have something for you. It's my little black book. It's got the numbers of all the guys I've dated. Rachel: Oh, Phoebe, that's nice, but you know what? I think I'm okay. Why don't you give it to one of your other single girlfriends. Phoebe: I would, but you're the last one. Rachel: Give me the book!
