J.D.: Perry, for the last time, we need more negative pressure rooms in the infectious diseases ward.
Dr. Cox: Huh, I didn't hear you knock.
J.D.: The door was open.
Dr. Cox: Then go outside, close the door, and knock.
J.D.: No, you're just going to lock it.
Dr. Cox: No, I won't.
J.D.: You know I've been burned before.
Dr. Cox: Believe in me.
J.D.: New chapter?
Dr. Cox: New chapter.
[later, as J.D. pounds on the locked door:]
J.D.: New chapter!
Dr. Cox: [answers phone] Perry Cox.
J.D.: We still need those rooms. And you sir, are a liar.
Dr. Cox: There is no money in the budget. And while you're delivering bad news, please tell Ted that he can't sing in pediatrics. A cappella music is, how to put this delicately... ear rape.
