One night, a cop was staking out a rowdy biker bar for possible DUIs.
At closing time, he saw a biker stumble out of the bar, trip over his own boots, and try his keys on five different Harleys before finally finding his own Harley.
He sat there in the saddle, fumbling with his keys for a few minutes while all the other bikers roared off into the night.
Finally, he fired up his engine and started to roll out. The cop was waiting. As soon as the biker hit the road, the cop pulled him over, read him his rights, and gave him a breathalyzer test. The result: 0.0.
The confused cop asked, “How’s that possible?” The biker grinned and said, “Relax, officer… tonight I’m the designated decoy.”
