One night, a police officer was staking out a particularly rowdy bar for possible violations
of the driving-under-the-influence laws.
At closing time, he saw a fellow stumble out of the bar, trip on the curb, and try his
keys on five different cars before he found his. Then the man sat in the front seat
fumbling around with his keys for several minutes. By this time everyone had left the bar
and drove off.
Finally, he started his engine and began to pull away. However, the police officer was
waiting for him.
The cop stops the driver, reads him his rights and administers the Breathalyzer test. The
results show a reading of 0.0% blood alcohol. The puzzled officer demands to know how
that could be.
With a smile on his face, the driver replies, "Tonight, I'm the designated decoy!"
