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 the pages of Leland Gregory's sharp offering, 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, though, everyone, everywhere is fair game if they've exhibited outrageously stupid behavior. Consider:

* The forgetful fireman who left cooking oil on the stove and returned from a call to find the station house burned to the ground.

* 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 Hebert, 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 will howl with laughter at the more than 200 examples of boneheadedness and buffoonery. Wise up and don't miss Hey Idiot!
