Quote from Rachel
Monica: Do you ever think Dad cheated on Mom?
Ross: Oh, no. I don't think so. 'cause that would involve having sex, and I would like to think that our parents don't do that sort of thing.
Quote from Ross
Ross: You see, that's where you're wrong! Why would I marry her if I thought on any level that she was a lesbian?
Roger: I don't know. Maybe you wanted your marriage to fail.
Ross: Why? Why would l? Why? Why? Why?
Roger: I don't know. Maybe low self-esteem? Maybe to compensate for overshadowing a sibling.
