Quote from Joey in The One with the Proposal (Part 2)
Joey: You know Chandler. Monica: No, I don't know Chandler. At least not anymore. It's like something's changed. Joey: Maybe you changed. Monica: I didn't change. Joey: Maybe that's the problem. Monica: What? Joey: Chandler is a complex fellow. One who is unlikely to take a wife. Monica: What does he think? Does he think that I'm just going to wait around for nothing? Joey: Monica, face it. Chandler is against marriage. And always will be.
