There were two hillbillies in a bar. They both had on overalls with no clothes underneath (including underwear). As they were drinking their beers, this lady started choking on some peanuts.
So the first hillbilly said to the other, "Quick pull down your overalls!" The second hillbilly does it and the first one starts to lick the second one's behind. Suddenly the lady stopped choking.
Upon witnessing what happened, the first hillbilly said, "See, I knew that Hind Lick maneuver would work!"
