His short fiction includes "The Little Black Bag," "The Marching Morons," "The Altar at Midnight," "Ms. Found in a Chinese Fortune Cookie," "Gomez," and "The Advent of Channel 12", "The Marching Morons" is his most famous short story; it is a satirical look at an overpopulated future, with a population consisting of a few geniuses and a huge number of stupid people, in which the few geniuses are working desperately to keep things running from behind the scenes. Part of its appeal is that readers tend to identify with the oppressed geniuses.
