Dancing With The Stars: Steve-O Hurts His Little Backy-Wacky Steve-O is a man who, for a fairly large chunk of his career, made a living by stapling his balls to his thigh. Steve-O is fearless. He sets his hair on fire. He lets people throw darts at him. He shoots fireworks out of his bottom with such confusing regularity that people often mistake him for Sydney Harbour Bridge. But even Steve-O's boundless physical endurance has its limits, which is why he ducked out of last night's Dancing With The Stars because he hurt his back. Next week: Johnny Knoxville quits Hell's Kitchen because an onion looks at him funny.
