Doctor Percival "Perry" Cox is a doctor at Sacred Heart in Scrubs played by John C. McGinley. Dr. Cox keeps a rough exterior and is very sarcastic even though he's always making his decisions to best help patients.
J.D. always looks up to Cox as a mentor but he preetends to hate J.D., even though he deep down things he's a good doctor. He is an avid sports nut and frequently is seen wearing a Detroit Red Wings jersey.
He was the interim Chief of Medicine after Dr. Kelso retired and before Dr. Maddox took over. He is expected to take back over this season.
J.D. [to Cox]: you won't admit this, but you're in love with Carla.
Carla: No, he's not.
Dr. Cox: Actually, I am.
Carla: You're starting again.
J.D.: And Carla, you're mad that Turk didn't trust you enough to tell you.
Turk: See? Trust, woman, trust!
J.D.: Whatever. The point is that Turk is sorry.
Turk: Not anymore!
Carla: I can't believe you thought he was a threat.
Dr. Cox: I'm a threat!
Carla: You're not in love with me, you idealize me.
J.D.: Can we just try and stay focused...
Turk: You're mad 'cause I'm scared of losing you?
Carla: Yes, because we're stronger than that!
Dr. Cox: Apparently not!
Ron: So look at you, Mr. Big Time Doctor!
Dr. Cox: How about you, Mr. Big Time...I don't actually know what you do.
Ron: Man, I've told you a hundred times: I run mergers and acquisitions for a large private equity hedge fund... You've forgotten already, haven't you?
Dr. Cox: No, no. You do hedge clippings for a big farm.
Dr. Cox: You privately acquire hedgehogs... Oh, come on, you got a hog farm. Gimme a break.
