Quote from Ross in The One Where Paul's the Man
Ross: Rachel's gonna need to yell sweet nothings in his ear. Chandler: Ross? Ross: Oh, come on! Guys, that's funny, you know? 'Cause he's got like a hearing aid, you know? 'Cause he's all old. [Paul starts laughing] Paul: One second. Okay, look, Ross. So you know, since Lizzie likes you so much I've decide to accept the fact that you are going out with her. Ross: Really? Okay, that's great. Paul: Yeah. But then I changed my mind. I'm funny like that. So I told Lizzie and now I'm telling you, I don't want you seeing my daughter anymore. Ross: All right, look. I realize it upsets you. Paul: Yes, it does. Ross: But Elizabeth and I are both adults so I don't think there's really anything you can do about it. Paul: I'll call the university and tell them about your relationship, and have you fired. Ross: Oh. A man with a plan!
