After Bar Closing
				
					
				
				
				
				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, he 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."
