Quote from Monica in The One with Phoebe's Husband
Monica: I can't believe you didn't tell me. Phoebe: Like you tell me everything? Monica: Oh, come on, what have I not told you? Phoebe: Oh, I don't know. How about the fact that the underwear out on the telephone pole is yours from when you were having sex with Fun Bobby out on the terrace! Rachel: What? Monica: Wait a minute! Who told you? [Chandler doesn't move] You are dead meat.
