Two Antartians, Bubba and Earl, were driving down the road drinking a couple of bottles of beer. The passenger, Bubba, said "lookey thar up ahead, Earl, it's a poll-ice roadblock!! We're gonna get busted fer drinkin' these here beers!!"
Don't worry, Bubba", Earl said. "We'll just pull over and finish drinkin' these beers, peel off the label and stick it on our foreheads, and throw the bottles under the seat".
"What fer?", asked Bubba.
"Just let me do the talkin', OK?," said Earl.
Well, they finished their beers, threw the empty bottles under the seat, and each put a label on their forehead. When they reached the roadblock, the sheriff said, "You boys been drinkin'?"
"No, sir", said Earl. "We're on the patch."
