6. Jon Elway / Gary Busey
Gary Busey is as crazy as the day is long. You may think that hes acting in those Amazon commercials that hes been appearing in lately, but thats not the case. He is literally that nuts, thanks in so small part to a drug habit in his previous life. It therefore probably doesnt make the legendary quarterback Jon Elway feel very good when people tell him that he resembles the great Gary Busey. Oh well!
