Lardass.

What the audience didn't know was that Lardass wasn't really interested in winning. What he wanted was revenge, and right before he was introduced he'd gotten ready for it. Diving into his fifth pie, Lardass began to imagine that he wasn't eating pies. He pretended he was eating cow-plops, and rat guts in blueberry sauce. Slowly, a sound started to build in Lardass' stomach. A strange and scary sound, like a log truck coming at you at a hundred miles-an-hour. Suddenly, Lardass opened his mouth, and before Bill Travis knew it, he was covered with five pies worth of used blueberries. The women in the audience screamed. Bossman Bob Cormier took one look at Bill Travis and barfed on Principal Wiggins, who barfed on the lumberjack that was sitting next to him. Mayor Grundy barfed on his wife's tits. But when the smell hit the crowd, that's when Lardass' plan really started to work. Girlfriends barfed on boyfriends. Kids barfed on their parents. A fat lady barfed in her purse. The Donnelley twins barfed on each other, and the Women's Auxiliary barfed all over the Benevolent Order of Antelopes. And Lardass just sat back and enjoyed what he'd created-a complete and total barf-o-rama!
