Quote from Phoebe in The Last One (Part Two)
Phoebe: Uh, Rach, hang on. Ross: [mouths] No, no, no. Rachel: Phoebe? Is everything okay? Phoebe: Um, actually no. No, you have to get off the plane. Rachel: What? Why? Phoebe: I have this feeling that something's wrong with it. Something is wrong with the left phalange.
