Two bikers walk into a roadhouse to wash the road dust from their throats. They stand at the bar, drinking a beer and talking about the new model Harleys.

Suddenly, a woman at a nearby table, who is eating a sandwich, begins to cough. After a minute or so, it becomes apparent that she is in real distress. 

One of the bikers looks at her and says, "kin ya swaller?" The woman shakes her head, no. "Kin ya breathe?" The woman begins to turn blue and shakes her head.

The biker walks over to the woman, lifts up the back of her dress, yanks down her panties, and slowly runs his tongue from the back of her thigh up to the small of her back. The woman is so shocked, that she has a violent spasm and the obstruction flies out of her mouth. As she begins to breathe again, the biker walks slowly back to the bar and takes a drink from his beer.

His buddy says, "Ya know, I'd heard of that there "Hind Lick Maneuver," but 'til today, I ain't never seen nobody do it."
