A cop saw a car weaving 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 liquor on her breath.

He said, "I'm going to give you a 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?"
