Quote from Phoebe in The One with Ross's Tan
Monica: Hi, Amanda. Actually, now is not a good time. Dinner tomorrow night? Okay, Phoebe and I will see you then. Phoebe: Why? Why? Why didn't you just say no? Monica: Well, I said no to her coming over now. I couldn't say no twice. I've got this uncontrollable need to please people. Phoebe: Fine. Fine. You would not hold up well under torture. Monica: Oh, and you would? Phoebe: I did.
