2 rednecks are out drinkin one night and tooling around in Junior's pickup...

They see a police road block up ahead, and his buddy Buford says, "Oh no, it's the cops, man... whatcha goin ta do?"
Junior pulls the truck over, takes the last 2 bottles of beer in the truck and says, "Let's drink these, but save the labels and stick em' on yer forehead"
"What? You crazy...", Buford protests.
"Jus do like I'm tellin ya", Jr. says, "I got me a plan..."

They finish and pull up to the road block, the officer comes to the window and looks at the 2 with the beer labels stuck to their forheads... "You boys been drinkin tonight??" he asks.

"Nah, we're on the patch."
