Quote from Ross in The One with Five Steaks and an Eggplant
Chandler: I'm not sorry I'm late. How incredible was my afternoon with Jade? Ross: Pretty incredible, according to the message on my machine. Hey, Chandler, why is this woman leaving a message for you on my machine? Chandler: Oh, see, I had to tell her that my number was yours because I couldn't tell her that my number was my number because she thinks my number is Bob's number. Ross: Hey, tell me again. What do I do again when Mr. Roper calls?
