Of the many begetters of reality TV, from ''Miss America" to Andy Warhol, Howard Stern remains the king of all influences. Before ''The Bachelor" became a craze, Stern was conducting steamy in-studio dating games that were unscripted and yet as theatrical as ''WWE Smackdown!"
Stern portrays himself as a brother geek to all nerdy men hopelessly dreaming of porn beauties, and that sensibility defined the dating show ''Average Joe" in 2003. Tonight at 8 on Channel 56, the WB and producer Ashton Kutcher try to breathe life into the same ugly-guy-pretty-gal genre with a reality series called ''Beauty and the Geek." Naturally, as the show's male Mensa members mix with voluptuous models, one shapely bimbo swears that Columbus discovered America in 1942. And just as naturally, the show is designed for the young male demographic.
