Here's some fun facts about everybody's favorite wookiee:
1) During filming of Return of the Jedi, Peter Mayhew was told not to wander around while in costume. They were on location in the California redwoods, and there was some concern he would be mistaken as Bigfoot by hunters and be injured.
2) Chewy almost wore pants! Studio suits wanted to put clothes on Chewbacca, because they were concerned that he's essentially naked. They kept sending notes and concept designs with Chewbacca wearing shorts and baggy pants. Lucas insisted on keeping Chewie a nudist. (See, George isn't all bad)
3) During the first Star Wars movie (A New Hope) Chewbacca carried a bag, which in the script reportedly contained tools and stuff for fixing the Falcon, but in actuality Peter Mayhew kept peanut butter and jelly sandwiches in it.
Now you, too can carry your PB&J sandwiches around in Chewie's bag. Or, rather a little bag that looks like Chewie. Nobody will dare try to take your lunch, because they know they might get they're arms ripped off if they do.
