"Donkey Punching, kids? You've heard people joke about it and other extreme and/or stupid sex acts. But while attempting your Hot Karls, Icy Mikes, or Louisville Pluggers is unlikely to result in injury, death, or incarceration, attempting a Donkey Punch can lead to any or all of these unpleasant outcomes. And not only is the Donkey Punch dangerous and likely to land your ass in jail, the damn thing doesn't even work."
