Quote from Phoebe in The One with the Videotape
Ross: Rachel won't talk to me. She won't even open the door. Phoebe: Hmm. I wonder why, pervert. Ross: Okay, listen, I am not a pervert. Phoebe: That's, like, the pervert motto. Yeah, they have you raise your right hand, put your left hand down your pants and repeat that.
