Quote from Phoebe in The One with the Ick Factor
Chandler: And this man-child has no problem with how old you are? Monica: No, of course not. It's not even an issue because I told him I was 22. Rachel: You what? Chandler: What? Monica: Oh, I can't pass for 22? Phoebe: Well, maybe 25, 26. Monica: I am 26. Phoebe: There you go.
