A blonde's car breaks down on the interstate one day.
So she eases it onto the shoulder of the road, carefully steps out of the car and then opens the trunk.
Out jump two men in trench coats that turn to face oncoming traffic and begin opening their coats and exposing themselves to approaching drivers.
Not surprisingly, this causes the highway's worst pileup to date.
Shortly the police show up. The cop, clearly enraged, runs up to the blonde and yells, "What the hell is going on here?"
"My car broke down," says the lady, calmly.
"Well, what are these perverts doing here by your car?" asks the cop.
"I've always been told when you're on the side of the road to use your emergency flashers!," she replied.
