Turk loves to dance and is definitely one of the best surgeons and makes it well known. His man love with J.D. is one of the best parts of the show.
J.D.: I can't believe she called me "sir."
Turk: She called me "mister."
Carla: Maybe it's because you're bald?
Turk: I'm not bald - I shave my head.
Carla: Well, then, let it grow back.
Turk: Careful, honey!
Turk: Alright Jake, here it is. The latest "Vengeance". I had to travel to five stores to find that.
Jake: This is last month's.
Turk: Look, I'll track down the new one for you later, but right now I've got to make sure I have a job next year.
