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.
Now, I'm real sorry I cold-cocked you there, Bob. I shouldn't have done that. Even if it did feel so damn good I changed my pants afterwards.Dr. Cox
J.D.: I already got my shifts covered for the next two days! Besides, where're you gonna find somebody else? You think Lonnie, my intern, gives a rat's ass about acute thomrobotic thrombocytopenic purpura?
Lonnie: ATTP? It killed my father.
Dr. Cox: You're in.
Lonnie: It is gonna be so amazing working on the disease that tore my family apart.
J.D.: Kiss ass.
