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.
Dr. Kelso: Perry, great news: I managed to swing it so that you get to go over to the state pen. today and do the annual inmates' physicals!
Dr. Cox: Well, hell's bells, Bobbo, if you want to fire me, just do it!
Dr. Kelso: I would, but even though this room was quite crowded when you sucker-punched me, apparently nobody saw it happen.
Ted snickers under his breath and Kelso glares at him.
Ted: Uh, saw what happen, sir?
Carla: You know what? I'm on my second glass of good wine, I'm watching my boyfriend try to eat his body-weight in meat, and I am extremely tickled that the only thing Dr. Cox wants isn't on the menu. Ha!
Dr. Cox: What?
Carla: Oh, what can I say? I'm finally having a good time.
Dr. Cox: That'll pass.
Todd: I still think it's pretty lame that you didn't like Turk's nurse practitioner present.
Dr. Cox: Told ya.
