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 blonde woman behind the wheel. There was a strong smell of 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 turned red, and replied, "You mean it shows that, too?"
