A blonde's car breaks down on the Interstate one day, so she eases it over onto the shoulder. She carefully steps out of the car and opens the trunk. Out jump two more blondes in trench coats, who walk to the rear of the vehicle where they stand facing oncoming traffic and begin opening their coats and exposing themselves to approaching drivers. Not surprisingly, one of the worst pile-ups in history of this highway occurs. It's not very long before a police car shows up.
The cop, clearly enraged, runs toward the driver of the disabled vehicle yelling, "What the devil is going on here?"
"My car broke down," says the lady calmly.
"Well, what are those blondes doing here by the road?" screams the cop.
"Those are my emergency flashers!" replied the first blonde!
