Quote from Joey in The One in Vegas (Part 1)
Joey: Hey, Pheebs. Listen, can you do me a favor? I forgot the PlN number to my ATM card. Can you get it for me? Phoebe: Sure. Where is it? Joey: Uh, I scratched it on the ATM machine on the corner. Phoebe: Oh, so you're 5-6-3-9? Joey: That's it! Thanks, Pheebs.
