A friend asked me to answer this question: What is the last name of the person who wants the world to go "caveman" for a day?, using the article: Roy Alston and Bo Richards are two outcasts of their high school community. Bo receives $200 as a graduation gift from his grandparents. Facing a lifetime of working blue collar factory jobs, the boys spontaneously decide to use the money to go on a vacation to Los Angeles. During the drive to Los Angeles, Bo and Roy rob a gas station and beat the attendant with a crowbar. The next day, the boys go to a beach boardwalk, where Roy throws an empty beer bottle and it hits an elderly woman on the forehead. Three young women (Claudia Templeton, Mary Tiffany, and Marilou Conway) see this, and they chase Bo and Roy to a parking lot. The women yell at the boys and damage their car. Enraged, Roy starts the car and drives around in circles in the parking lot with the women still on the hood. After several loops, Roy throws the car into reverse, throwing one of the women from the hood of the car. After the incident, one of the women finds Bo and Roy's dog, Boner the Barbarian, and reads its ID tag, which leads to speculation of where Bo and Roy are from. During a visit to La Brea Tar Pits, Bo expresses his wish that the world could just "go caveman" for one day, abandoning all rules and order. Roy agrees, and they spend their evening on the streets of Los Angeles., what would be the answer ?
A:
Richards
