A blonde's car gets a flat tire 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. Takes
out two cardboard men, unfolds them and stands them at the
rear of the vehicle facing oncoming traffic. The lifelike
cardboard men are in trench coats exposing their nude bodies
to approaching drivers...

Not surprisingly, the traffic became snarled and backed up.
It wasn't very long before a police car arrives.

The Officer, clearly enraged, approaches the blonde of the
disabled vehicle yelling, "What is going on here?"

"My car broke down, Officer" says the woman, calmly.

"Well, what are these obscene cardboard pictures doing here
by the road?!" asks the Officer...

"Oh, those are my emergency flashers!" she replied.
