Quote from Ross in The Last One (Part Two)
Phoebe: Hey, do you realize that at one time or another we all lived in this apartment? Rachel: Oh, yeah. That's true. Ross: Uh, I haven't. Monica: Wait a minute. What about that summer during college that you lived with Grandma and you tried to make it as a dancer? Ross: Do you realize we almost made it ten years without that coming up?
