What do you do if your best friend is Keith Livingston? Keith -- who practically needs a chart to keep track of his babes. Keith -- the stud/athlete/Adonis of Hannaford School in New York City. Well, for starters, if you"re like Matt Greene, a 5"1" nerd who has never made out, you suffer. When Keith"s eighth-grade musical, Star Crossed, is a smash, Matt can"t take it anymore. Blowing off steam on the corner of Eighty-first Street and Columbus, he wishes his buddy"s life would fall completely apart. Sound serious? As Matt"s story shows, the insane, gut-wrenching jealousy of a non-stud/non-athlete/non-Adonis basket case can be wildly funny.
