The Alabama (but could also be other Southern states) Vasectomy
Billy Bob and his wife had 6 kids and decided this was enough. His wife told Billy Bob that he should get a vasectomy, and he agreed.
The next day, Billy Bob walked down to the doctor in Crossville and asked about the procedure.
"Well" said the doctor, "it's a very simple procedure. Take an empty beer can, put an M-80 firecracker in it, light it and then hold the can and count to 10".
That can't be right, thought Billy Bob. So, he asked if he could seek a second opinion. The doctor told him that he should go to Vanderbilt Hospital in Nashville and ask a doctor there. So he did.
He traveled on the bus and got to the doctor's office. When he was invited into the consultation room he asked the doctor about a vasectomy.
"Oh, it's very easy," said the doctor. "Take an empty beer can, put an M-80 firecracker in it, light it and then hold the can and count to 10".
Now with two doctors saying the same thing, Billy Bob thought this must be the correct way to do it. He went home and bought himself a case of beer. After 2 or 3 cans to get rid of the nerves, he went into the garden, placed an M-80 in an empty beer an and lit it. Then he started counting.
"One, two, three, four, five..."
Then he ran out of fingers on one hand. So he gripped the beer can between his thighs and started to count on the other hand.
