Who Is Joey Pants?

Someone keeps 'modifying' the lobby photos of the air-staff here at the radio station. A few weeks ago, the jerkiest Star Trek character (C3PO), was plastered over my picture; Princess Leia's hair showed up on Nick Chase's photo and Chewbacca's furry face replaced the fine image of my radio partner Joey Pants.

There's been an update.

Nick's addition is obvious. I have been covered with Eddie Van Halen at seemingly the lowest point in his life.

The question, though, is whose face has replaced Chewy on Joey's photograph? Any idea?
