Quote from Monica in The One with Ross's Tan
Monica: I can't believe you tried to cut me out. Why, Phoebe? Why? Phoebe: It was right after we were living together and you were driving me crazy, okay? You were really controlling and compulsive and shrill. Monica: Well, I'm still all those things. Phoebe: You're also so generous and kind and scrappy. Monica: I am scrappy. Phoebe: Exactly. Look, no matter what I tried to do, I couldn't keep you out of my life. Of all the people I've cut out you were the only one who ever clawed her way back in. Monica: That's because I'm scrappy.
