From what I hear, billy is so such a work-a-holic that he only takes a shower every 2 or so months. That would explain that look one everyones face around him, plus if one of them said anything about it, the guards would probably break their arms and legs.
I like Billy G - I'm not a MS hater at all - but I've heard that his smell is sometimes so bad his co-workers have to mention it to him. Wouldn't that be fun... "Uh, Bill, uh you take a shower this month yet? Maybe you should. You don't think you need to? Uh, OK Bill thazz fine."
