"Jackass" star Steve-O was accompanied to the Stern Show studio by a friend named Walter on Thursday and explained the stunt he'd planned: Steve will spit a fireball as he flips, lighting his hair on fire in the process. Then Walter will spit more fire on his chest.
Howard expressed concern for the plan, but Steve told him not to worry, and reminded him that he was a graduate of the Ringling Bros. and Barnum & Bailey Clown College.
Howard continued to protest as Steve-O set up, asking, "Have you ever tried this before?"
Steve laughed and told Howard, "Sort of." He then flipped, fire flying everywhere.
Robin couldn't believe the aftermath. "He's still smoking!" she exclaimed.
