It's not feelings of superiority that make us suspect the universe is filled with dumb people: The universe really is filled with dumb people, as it's easy to see in Leland Gregory's Hey Idiot! Gregory, a former Saturday Night Live writer, is the smart cookie who's previously showed us gray matter-challenged examples in everything from the criminal world to the hallowed halls of government. This time, everyone, everywhere is fair game if they've exhibited outrageously stupid behavior. Consider: The forgetful fireman who left cooking oil on the stove and burned the station house down; A lung cancer patient who caused an explosion when he lit up a cigarette - in his oxygen tent; A 58-year-old billiards player who was suspended from competition after testing positive for a muscle-building hormone; F. Edward Herbert, chairman of the House Armed Services Committee, who said, "The only way we'll get a volunteer army is to draft them." Hey Idiot! lets everyone from bosses to public officials, doctors to sports heroes, skewer themselves with their moronic words and action. Readers - and there are loads of them who can't turn away from "America's funniest and dumbest" TV shows - will howl with laughter at the more than 200 examples of boneheadedness and buffoonery.
