Quote from Ross in The One With Ross's Step Forward
Ross: Okay. I'm gonna need a bunch of extra keys. Apparently, I give them away for no reason at all. Mona: Hey, Ross, what's going on? You're changing the lock? Ross: No. That guy is. Mona: I don't understand. You give me a key to your apartment, and then you change the lock? Ross: Uh- Locksmith: Good luck, buddy.
