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.
(to Turk) Look, surgeons always want to slice people open whether it's the best option or not. No disrespect, but you're just not that bright, you have no idea how to do anything else. Unfortunately, sick people are also very, very stupid and almost always agree to anything that a blood-letting corpse carpenter, such as yourself, tells them. I simply stay in the room to make sure they make the right choice.Dr. Cox

J.D.: "Stringent updoc". It's happening.
Dr. Cox: Yes, Nervous Guy?
Doug: What's "updoc"?
