Try out this one:
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 blonde, calmly.
Well, what the hell are these obscene cardboard
pictures doing here by the road?!" asks the Officer...
"Helllllooooo, those are my emergency flashers!" she
replied.
