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 men in trench coats, who walk to the rear of the vehicle
where they stand facing on-coming 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 blonde driver of the disabled vehicle yelling,
"What the hell is going on here?"

"My car broke down," she says calmly.

"Well, what are these perverts doing here by the road?" screams the cop.

"Those are my emergency flashers!" replied the blonde!
