Monica: Y'know what? What if we're friends who don't see other people?
Richard: You mean like... exclusive friends?
Monica: Why not? ...I mean, this has been the most amazing week. Would it be so terrible? ...even if we were friends who lived together? ...or, maybe someday friends who stood up in front of their other friends, and vowed to be friends forever?
Richard: Wow. You know we're back where we were... Honey, I would love to do all that, but nothing's changed...
Monica: That's not true. You don't have a mustache.
