The actor who plays Turk is playing tonight at 7:00 ET along with Zach Levi of Chuck and Michael Rapaport of Prison Break, along with countless 篮球 veterans.
I'm not 100% sure about this, but I saw the episode, and the ad shortly after. Turk wears this in "My Inconvenient Truth" when he paints his face like a 篮球 and JD asks him if he needs to grow up.
