Quote from Ross in The One with the Girl from Poughkeepsie
Phoebe: If she's no fun, why date her at all? Ross: Well, I want to give her another chance. She lives so close. And, at the end of the date, she said something that if she was kidding, was very funny. On the other hand, if she wasn't kidding, she's not fun, she's stupid and kind of a racist.
