Zach Braff plays the monkey butler in "The Wizard of Oz" with James Franco. Try not to destroy him, too much.
He's probably not racist, just a little clueless is all. Turk is facepalming somewhere, though.
I thought Pharrell dressed as a bellhop was super coonish to begin with, so I'm more offended that he would choose to perform in that outfit, rather than Zach's comment.
