Quote from Phoebe in The One After 'I Do'
Phoebe: Are you ready to talk about it? Rachel: No. Phoebe: Now? Rachel: No! Phoebe: Okay, we'll talk about something else. Who's the father? Rachel: Look, honey, I haven't told him yet, so until I do I don't think I should tell anybody else. Phoebe: Yeah. That's fine. That's fair. Is it Tag? Rachel: Oh, Phoebe. Phoebe: I'm sorry, I'll stop. Is it Ross? It's Ross isn't it? Oh, my God, it's Joey! Rachel: Stop it, okay. I'm not going to tell you until I tell him. Phoebe: Aha. At least we know it's a him.
