Have you ever seen the guy who was in the Chewbacca costume?
Notice that he's wearing a Chewbacca shirt. I saw a documentary* recently where he was wearing a Chewbacca leather duster AND a Chewbacca top hat!
From the looks of things, it's probably a good thing that costume didn't have a kid-raping hole in it.
*it was, in fact, a "Star Wars" documentary. He's obviously all about Chewbacca, so I don't think he'd really be involved in documentaries on other subjects.
