I'm all about not judging a book by it's cover. Some of the nicest people I've ever met looked like they'd slit your throat given half a chance - but volunteered to give their time to the local nursing home to read to and visit with some of the old folks, and some of the nastiest (and I mean downright spiteful verging on wickedly evil) were clean cut jocks who went to church on sundays - but who liked to torture animals and small children in their spare time.
So rock on, all my mohawk wearing, inked and pierced friends.....and may Brian live forever in the hearts of those who loved him.
