Quote from J.D. in His Story
J.D.: [v.o.] Turk's relationship is so messed up right now I decided to lighten his mood. And nothing cracks him up more than the old, block-the-door-with-my-foot gag. [Carla walks into the door] Oops, wrong person. Carla: What happened? J.D.: The door must have got stuck. Gotta go.
