A policeman has a bar under surveillance, shortly before closing time, so he can nab anyone who attempts to drive away drunk.
The first guy out the door at 2:00 o'clock weaves down the sidewalk and falls off the curb. He struggles to his feet and then tries his key in five cars before finding his own.
Once inside his car, he fumbles with the keys for several minutes. Meanwhile, all of the other bar patrons have gotten into their cars and driven away, leaving this one guy alone on the dark street.
Finally, he gets his car started and begins to very slowly pull away from the curb. Immediately, the police car pulls up behind him with lights flashing.
The policeman asks the man to get out of the car and take a field sobriety test, which he easily passes. Confused, he then asks the man to take a Breathalyzer test, to which he readily agrees. When he blows a perfect 0.0%, the policeman said, "How can this be?" The man replies, "Because tonight, officer, I'm the designated decoy."
