Zap! One day you are the coolest kid wearing the coolest clothes. Suddenly, your hair is parted drastically to one side, inside the front pocket of your checkered shirt is a pocket protector, and old disco is the music of choice. What happened? You were just stung by the Nerdfly. Tired of being a target to every school bully, Hal Slagel helps a 'whiz kid' friend build the ultimate payback--The Nerdfly. A simple sting from the electronic insect will send any bully into a personality tailspin for eight hours. It's all perfect until the Nerdfly flies out of control. Teachers, policemen, mechanics ... no one is immune when the Nerdfly goes amuck, stinging everyone in town.
