Two police cars pull up and park across the street from the parking lot.

About ten minutes later they see a man walk out of the bar so intoxicated that he can barely walk.

The guy stumbles around the parking lot for a few minutes while they watch.

After what seems an eternity trying his keys on five different vehicles, the man manages to find his own car.

He falls into it, and as a number of other patrons exit the bar, starts his car.

He switches the wipers on and off (not a cloud in the sky), and backs half out of his parking spot, pausing as other cars pull around him.

As more people leave the bar, he flicks the hazard lights on and off, toots the horn and then switches on the headlights.

He starts to pull forward to avoid the last of the cars leaving the bar, then finally backs out of the parking space.

The cops just watch, shaking their heads in disbelief.

At last he pulls out of the parking lot, turning his headlights off, then on again, and starts to drive slowly down the street.

The police, having patiently waited all this time, flip on the lights and siren, and pull the man over.

Unbelievably, the man passes all dexterity and coordination tests as if he were completely sober.

They ask if he would mind taking a breathalyzer test and he replys affirmatively.

After attempting it several times with only negative results one cop surmised that it might be broken.

Looking up from his seat on the curb the man says, "I doubt it, Tonight I'm the designated decoy."
