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.
Elliot: I don't think you understand the severity of the situation here! I am dangerously close to giving up men altogether!
Dr. Cox: And on behalf of men everywhere - and I do mean everywhere, including the ones in the little mud huts - let me be the first to say thanks and halleluia!
