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.
J.D.'s Narration: Still, even if you end up with a hangover that would slay a walrus, it's all worth it. Especially when you know that at this very moment your best friend is at lunch saving his marriage.
Turk: What time is it?
J.D.'s Narration: Or he missed it.
Turk: Dude, it was awful. I couldn't stop lying to them. I only have two moves! If surgery goes well, the fake modest nod and wink. Now, if surgery goes bad and the guy dies, there's always the headshake-sad-walk-away.
J.D.: Turk! Toto and I are going home.
J.D.: Okay! I'll help!
