"Redneck First-Aid" joke

Two Southerners were having the blue plate special at their favorite
watering hole, when they heard an awful choking sound. They turned
around to see a lady, a few bar stools down, turning blue from wolfing
down a Specialty Burger too fast.
The first Southerner said to the other, "Think we otta hep?"
"Yep," said the second.
The First Southerner got up and walked over to the lady and asked,
"Kin yew breathe?"
She shook her head no.
"Kin yew speak?" he asked.
She again shook her head no.
With that he helped her to her feet, lifted up her skirt and licked
her on the butt. She was so shocked that she coughed up the
obstruction and began to breathe with great relief.
The First Southerner turned back to his friend and said, "Funny how
that there Hind Lick Maneuver works ever' time."
