A car breaks down along the motorway one day, so the driver eases it over onto the shoulder of the motorway. He jumps out of the car, opens the trunk, and pulls out two men in trench coats.

The men stand behind the car, open up their coats and start exposing themselves to the oncoming traffic. One of the worst pile-ups in history occurs.

When questioned by police why he put two deviates along the side of the road, the man replied, "I broke down and was just using my emergency flashers!"
