J.D.: Sometimes Dr. Cox is all over me, like every second of my life.
Murray: Why do you keep talking about your boss like he's your father?
J.D.: Remember? Recently deceased dad?
Murray: Massive heart attack.
J.D.: Yes! I mean, yes.
[meanwhile:]
Dr. Cox: You do know he's not yours, don't you?
Mr. Marks: I figured it out. Mostly because his mother was eight months pregnant when I met her. But there were other signs.
Dr. Cox: 'course.
Mr. Marks: But his real dad was such a jerk we just decided not to tell him. A boy needs a father who loves him, you know?
Dr. Cox: Yeah.
