Recently, a routine police patrol was parked
outside a local neighborhood bar in Minnesota. Late
in the evening, the officer noticed a man leaving the
bar so intoxicated that he could barely walk.

The man stumbled around the parking lot for a few
minutes with the officer quietly watching.

After what seemed an eternity and trying his keys
on five different vehicles, the man managed to find
his own car which he fell into.

He was there for a few minutes as a number of other
patrons left the bar and drove off. Finally, he
started his car, switched the wipers on and off (it
was a dry night), flicked the hazard flasher on and
off, tooted the horn and then switched on the lights.

He moved the vehicle forward a few inches, reversed
a little and then remained stationary for a few more
minutes as more patrons left in their vehicles.

At last he pulled out of the parking lot and
started to drive slowly down the street. The police
officer having patiently waited all this time, now
started up his patrol car, put on the flashing lights,
promptly pulled the man over and carried out a
breathalyzer test.

To his amazement the breathalyzer indicated no
evidence that the man consumed 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," said the man. "Tonight I'm the
designated decoy."
