Recently a routine police patrol was parked outside a bar in the Outback. After last call, the officer noticed a man leaving the bar so apparently intoxicated that he could barely walk. The man stumbled around the parking lot for a few minutes, with the officer quietly observing. After what seemed an eternity, in which he tried his keys on five different vehicles, the man managed to find his car and fall into it.
The police officer, having waited patiently all this time, now started up his patrol car, put on the flashing lights, and promptly pulled the man over and administered a breathalyzer test. To his amazement, the breathalyzer indicated no evidence that the man had consumed any alcohol at all! Dumbfounded, the officer said, "I'll have to ask you to accompany me to the police station. This breathalyzer equipment must be broken."
"I doubt it," declared the man with pride. "Tonight I'm the designated decoy."
