Buford and Buck 2 redneck boys in the next booth notice she is choking. So they get up and go over to help her. Buford drops his coveralls and bends over and then Buck starts licking his butt.
The choking woman watches these two go at it and is so grossed out she starts spewing up all over the place, dislodging the chicken bone from her throat.
Buford pulls his overalls back up and says to Buck "You're right, that hind-lick maneuver works like a charm."
