Breathalyzer Test

A police officer was making his daily round. Suddenly, a red corvet passed by him at a 100 m/h. He went after the car and stoped it. As he walked towards the car's window, he noticed that the driver was a gorgeous blond. He went to her and asked for her driver's licence and registration papers. The women kinda looked confused, but after emptying her bag, she handed the papers to the officer. He walked backed to his car and checked with another officer about the car's license plate. The other man asked him if the driver was a gorgeous blond. The first officer said yes. The second one then told him to go back to the corvet and pull down his pants. Without arguing, he went back to the girl and pulled down his pants. The girl than replied: "Ah! Not another breathalyzer test!"
