Dumb Blonde

A blonde's car breaks down on the Interstate one day. So she eases it
over onto the shoulder of the road. She carefully steps out of the car
and opens the trunk. Out jump two men 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 pileups in history of this highway occurs.
It's not very long before a police car shows up.
The cop, clearly enraged, runs toward the blonde of the disabled vehicle
yelling, "What the hell is going on here?

"My car broke down," says the lady, calmly.

Well, what are these perverts doing here by the road?" asks
the cop. "Those are my emergency flashers!" she replied.
