Notes At the L.A.Con I masquerade, one of the contestants, artist Scott Shaw!, came on stage wearing only a bathing suit, with his body completely covered with crunchy peanut butter. The name of his costume was "The Turd." from an underground comic story Shaw wrote and illustrated. Since some of the peanut butter tended to drip off of him, making the floor sticky for other contestants, a rule was passed that forever after at science fiction convention masquerades, no peanut butter costumes would be allowed. This masquerade rule is universally known among science fiction fans as the "no peanut butter rule." The first video game competition at a science fiction convention was held, and a science fiction fan named Kevan Pritchard from Lawndale, California, won the world championship contest in the game Spacewar!.
