A cop saw a car waving all over the road and pulled it over. He walked up to the car and saw a nice-looking woman behind the wheel. There was a strong smell of liquor on her breath.

He said, "I'm going to give you breathalyzer test to determine if you are under the influence of alcohol." She blew up the balloon and he walked it back to the police car. After a couple of minutes, he returned to her car and said, "It looks like you've had a couple of stiff ones."

She replied, "You mean it shows that, too?"
