One night a patrolman
was staking out the local bar on the lookout for drunk drivers.
At closing time, he saw a man stumble out of the bar, trip over
the curb, and try his keys in five different cars before he
found his own.
Then he sat in the front seat fumbling
around with his keys for several minutes as everyone else was
driving away. Finally, he started the engine and began to drive
off.
The cop was waiting for him and stopped
him right away and gave him a breathalyzer test. The results
showed a reading of 0.0.
The puzzled officer demanded to know how
that could be: "You were acting as drunk as a
skunk!"
The driver replied, "Well Officer,
tonight I'm the designated decoy."
