Pa Trooper
 

A young woman was pulled over for speeding. As the Pennsylvania State Trooper walked to her car window, flipping open his ticket book, she said, " I bet you are going to sell me a ticket to the State Troopers Ball."
He replied, "Pennsylvania State Troopers don't have balls".
There was a moment of silence while she smiled, and he realized what he had just said. He then closed his book, got back into his patrol car.
