Hank Azaria Shaves His Head (PHOTO)

Actor and "Simpsons" voice Hank Azaria has shaved his head.

He had a full head of hair last week, but Monday night showed up at the Geffen Gala with nary a hair on his head.

No word what it's for, but he has been cast as Gargamel in The Smurfs.

What do you think?
