Three rednecks are driving around one night drinking beer and having a great time. About two hours into their drinking they see a police roadblock up ahead. The two passengers start to panic. The driver tells them to settle down and do what he does as he peels off the beer label from a bottle and sticks it on his forehead. Both guys look at him as if he is nuts but figure they've got nothing to lose and do the same. The driver approaches the roadblock, slows down and rolls down his window.

The cop looks in and the smell of beer just pours out of the car.

He asks "You boys been drinkin?"

The driver all serious points to his forehead and says "No sir! We're all on the patch!"
