[After the Janitor gets in the elevator with them, Turk and J.D. bust out laughing:]
Janitor: Yuk it up, I don't care. I'm getting the last laugh. 'cause my brother's waiting for me downstairs and when these elevator doors open, you'll see, he's gonna be staring right at you two guys.
[elevator doors open; nobody is standing there]
Janitor: Okay, I don't know what I thought was gonna happen, but I think we can all agree that this isn't working out. It's costing me a tremendous amount of time and effort, so let's just call it a draw.
Turk: Hell, no! You lost. Live with it.
