Quote from Monica in The One with Phoebe's Rats
Monica: What's the big deal with her? Maybe she's attractive in an obvious kind of way. Ross: Yeah, obvious beauty's the worst. You know, when it's right there in your face. Me, I like to have to work to find someone attractive. Makes me feel like I earned it. Chandler: Looks like Joey's doing all right with her. Monica: Yeah. Hey, that was nice of you guys to back off and let Joey get the girl for once.
