Not surprisingly, one of the worst pileups in history of this highway occurs and it's not very long before a police car shows up. The cop, clearly enraged, runs toward the idiot who was driving the disabled vehicle and yells, "What the hell is going on here?"
"My car broke down," says the idiot, calmly.
"Well, what are these perverts doing here by the road?!" asks the cop.
"Those are my emergency flashers!" he replied.
