Jimmie Walkerstein, the inventor of the JI-AT All-Terrain "Jimmie" Walker, was famous for having destroyed his planet with dyn-o-mite, for which he was posthumously awarded a Nobel prize. Tragically, he was killed the night before the ceremony by Cassus Fett the Lesser, who beat him to death with a peanut butter jar for winning a sabacc card game. The vehicles, however, were rendered obsolete by Sesame Street, with many being converted into lunchboxes for children. Others found use as heavy ice cream trucks by intergalactic fast food chains.
