Doctor Christopher Duncan Turk, who's mostly known as just Turk, is played by Donald Faison and is J.D.'s best friend on Scrubs. He is a surgeon at Sacred Heart and quickly dates and marries one of the nurses there, Carla Espinosa. He and Carla then have a baby Isabella together.
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.
Dr. Cox: So, Nurse Ghandirella, I need you to suction this guy, do a wet-to-dry dressing change, and, oh, what the hell, go ahead and top him off with one of your special, special sponge baths - happy ending optional, his choice, not yours.
Turk: This guy's in a coma.
Dr. Cox: Not all of him.
Todd: Well, seriously, why wouldn't you want a better job?
Turk: Hold up. My Baby's happy with being just a nurse. Did I say "Just a nurse"? I didn't mean "just a nur-". Nobody at this table said "just-". I meant: "A Nurse." Right, Baby?
Carla: That's right!
Dr. Cox: Oh, just not smart. Even for you.
