Monica: (about Joey's new roommate Janine) ...And you better watch the flirting, too, because, y'know, in such close quarters... it could be trouble.
Joey: Well, that's going to be tough, Mon. I mean, it's hard for me to be around an attractive woman and not flirt.
Monica: (amused) Well, you're around me all the time and you don't flirt...
Joey: (seductively) You a little sad about that, sweetheart?
