Quote from Dr. Green in The One with the Stripper
Dr. Green: So, sweetie, you were starting to tell me what is new with you.
Rachel: Well ... Um ... I got TiVo.
Dr. Green: What's TiVo?
Phoebe: It's slang for "pregnant."
Dr. Green: Are you really pregnant?
Rachel: Well, yes and no. Except, not no. So to sum it up, yeah.
Dr. Green: Who is the father? Oh, no, please don't tell me it's her.
Rachel: No, it's Ross. It's Ross. You like Ross. Oh, Daddy, I hope you're okay with all this. I mean, this is a good thing. Think about it, this is your first grandchild! You're gonna be a poppy.
Dr. Green: That's true. I'm a poppy. I'm gonna be a poppy! So when is the wedding?
Rachel: The who?
Dr. Green: The wedding. There's going to be a wedding. Young lady, don't you sit there and tell me my first grandchild is gonna be a bastard! Rachel Karen Green, tell me there's gonna be a wedding!
Rachel: February 2nd.
