Quote from Rachel in The One with Phoebe's Rats
Rachel: But first, Monica, I would like to introduce you to my very talented colleague and more importantly my wonderful friend, Gavin Mitchell. Gavin: Pleased to meet you. Monica: Pleased to meet you. So are you coming to Rachel's party? Rachel: Oh, no, no, no, no. Gavin can't. He already has plans, most likely with his mother.
