A Highway Patrolman waited outside a popular bar, waiting for a bust.
At closing time, everyone came out and he spotted his potential quarry.
The man was so obviously inebriated that he could barely walk.
He stumbled around the parking lot for a few minutes, looking for his car and, after trying his keys on five other vehicles, he finally found his own car.
He sat in the car for a good ten minutes while the other patrons left. He turned his lights on, then off, wipers on, then off.
He started to pull forward onto the grass, but then stopped. Finally, when every other car had gone, he pulled out onto the road and started to drive away.
The patrolman, waiting for this, turned on his lights and pulled the man over.
He administered the breathalyser test, but to his surprise, the man registered a zero. He wasn’t drunk at all!
The patrolman was dumbfounded. “The equipment must be broken!” he exclaimed.
“No, it isn’t,’ smiled the driver. ’I’m the designated decoy.”
