J.D.: Have you guys been fake-laughing at my jokes? Be honest. I promise, absolutely no ramifications.
Keith: Well, we've been kind of fake-laughing.
J.D.: Keith, I hope you die a violent death and bugs eat your corpse.
Keith: Look, your jokes kind of suck, and when I laugh, you pick me to do procedures.
J.D.: Unbelievable. From now on, there is absolutely no laughing at my jokes unless they're particularly hysterical. Talk about your Mission: Impossibles. [chuckles]
Janitor: Case closed.
J.D.: What is it with you and costumes today?
Janitor: I borrowed it from my brother. He's a stripper.
