Mother in law race
A car race, often held in conjunction with a demolition derby, e.g. at a county fair. The cars are junkers. The drivers are blindfolded (yes, blindfolded). There's a second person in the back seat of each car, the "mother in law", who shouts directions at the driver. "Gas!" "Left!" "Brake!" Hilarity ensues.
