Quote from Phoebe in The One with All the Cheesecakes
Phoebe: Joseph Francis Tribbiani, are you home yet? Rachel: Um, I think he's still out. What's wrong? Phoebe: Well, I'll tell you, Rachel Karen Green. I had plans with Joey tonight, and he left me this note. Rachel: "Pheebs, can't make it. Got a date. Talk to you later. Big Daddy." "Big Daddy"? Phoebe: Oh, that's a nickname we were trying out.
