Quote from Rachel in The One with Phoebe's Cookies
Phoebe: So, what do you guys want for an engagement gift? Chandler: That's okay, Pheebs, we're not having a party, so you don't have to- Monica: [stammering] If someone wants to give us a present, we don't want to deprive them of that joy. Rachel: Oh, you know what you should get them, one of those little portable CD players. Monica: Oh, I already have one. Phoebe: Unless someone borrowed it and left it at the gynecologist. Rachel: Yeah, and by "someone" she means Joey.
