A guy is cruising along in his car when the car breaks down on the expressway.

The driver pulls over to the shoulder of the road, jumps out of the vehicle, then opens the trunk - out pop two men in trench coats.

The men stand behind the car, open up their coats, and begin exposing themselves to oncoming traffic. The result is a terrible pile-up.

A police officer arrives on the scene and surveys the carnage.
He screams at the driver: "Why on earth did you put these two perverts at the side of the road?"

The driver explains: "I broke down, and I was just using my emergency flashers."

good one Dan
