[Steve-O], now 28, studied at the Ringling Brothers and Barnum & Bailey Clown College in Florida several years ago, but there was no vestige of this training obvious on Sunday. Instead, Steve-O merely tried to shock fans through feats of self-abuse that were slight of mind, not sleight of hand. Early in the set, for example, he snorted salt through his nose, which made him vomit. "I'm kicking my own [butt] every day because I love you guys," he told the packed house, before stapling to his body an assortment of bras and panties that had been thrown to the stage by fans up front.
