Hanna-Barbera's Dexter's Laboratory told the story of Dexter, a bespectacled young boy who just happened to be a genius. The title referred to the enormous laboratory Dexter built in his room, unbeknownst to his parents. But despite his tremendous I.Q., Dexter could never figure out a way to ward off the plague that was his annoying older sister, Dee Dee.
