(Dr. Cox enters the room from the room of a patient he cannot diagnose)
J.D.: So Turk, yesterday i had this patient I could just not diagnose.
Turk: Wow you must have felt like a real jackass.
J.D.: I did feel like a jackass, but then I was able to figure out what was wrong with them because I'm not a jackass, I'm a good doctor... Oh hey Dr. Cox, how are things?
