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 girl behind the wheel. There was a strong liquor smell all over the car.
"I am going to give you a Breathalyzer test,” he said. “That will show whether or not you are under the influence of alcohol.”
She blew up the balloon and the cop walked it back to the police car. After a minute or two, he returned to the girl’s car. “Well, it looks like you’ve had a couple of stiff ones,” he said.
“You mean it shows that too?!?!” she asked, surprised.
