Another Blonde Joke

[Sonny]

One day a Blonde was going down the road in her car when she sees a car accident. She comes to a stop 2 miles down the road because she hit the gas instead of the brakes.
The Blonde then proceeds to pull out 2 naked cardboard men that she put long coats on. She then sets them up along side the road.
After an hour passes and traffic backs up 12 miles, a cop comes by. The cop pulls over onto the side of the road. He steps out and asks the woman what those cardboard things are for. She says, "Oh nothing sir, these are just my emergency flashers."
