A Policeman pulls a blonde in a sports car over for speeding and is trying to explain to her what and where her driver's license might be. After she eventually gives him her driver's license, he asks for registration.
Getting another blank blonde look from her, he explains, "It's that little piece of paper you get with your car and you keep it in the glove compartment."
"Ah," she says as she bends over to get it. While she is looking through the glove compartment, the officer unzips his pants and pulls his member out.
Excited that she had found her registration, she turns around and looks up. A look of dismay crosses her face and she says, "Oh, no! Not another breathalizer test!"
