J.D.: What's wrong?
Janitor: I lost my mop.
J.D.: Really?
Janitor: No. But that's the only thing that could make me unhappy, right? You people, you think of me as nothing but The Janitor.
J.D.: That's not true.
Janitor: What's my name? [covers name badge]
J.D.: I know that the nurses call you Sir Plunge-a-lot.
Janitor: I know.
J.D.: Come on. I'm sure you don't know my name so-
Janitor: John Michael Dorian.
J.D.: How did you know my middle name?
Janitor: Because I care.

J.D.: Look, Dr. Cox, I've been doing a lot of thinking, and honestly I think the only reason you're not down at that hospital right now is that you're afraid.
Dr. Cox: I think you're right. I do. That's partly because you've really gotten to know me this year, but mostly it's because, well... I told you that I was afraid earlier, so please don't tell me you've come here to reiterate to me things I've already said, because I know the things that I've already said. In fact, I'm the one who said them.

J.D.: You've got to get back in the game, Coxie. Okay, "Coxie" was a mistake. Pretend I didn't say Coxie.
Dr. Cox: Get out.
J.D.: Look, I It boggles my mind that you would just bail on a patient.
Dr. Cox: A patient is a stranger in a bed that you can distance yourself from when you need to. Ben is my friend. I'm gonna try to visit him over the next couple of weeks, but if I can't, then that'll be very sad for me, but really, it'll just mean that I'm human. Oh, and Newbie, please don't think that you've come here because Ben needs me. You're here because you're scared to death that you might have to rely on yourself for the first time. And that... That is just the saddest thing of all.
