One night, a police officer was stalking 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, sat in the front seat
fumbling around with his keys for several minutes.
Everyone left the bar and drove off. Finally, he started his
engine and began to pull away.  
 
The police officer was waiting for him. He stopped the driver,  
read him his rights and administered the Breathalyzer test.  
The results showed a reading of 0.0. The puzzled officer 
demanded to know how that could be.  
The driver replied, "Tonight, I'm the Designated Decoy."
