After having their 11th child, an Alabama couple decided that was
enough (they could not afford a larger doublewide).  
So, the husband went to his doctor (who also treated mules) 
and told him that he and his wife/cousin didn't
want to have any more children.  The doctor told him that 
there was a procedure called a vasectomy that could fix
the problem.

The doctor instructed him to go home, get a cherry bomb (fireworks
are legal in "Bama"), light it, put it in a beer can, then hold the can
up to your ear and count to 10.  The Alabamian said to the doctor, 
"I may not be the smartest man, but I don't see how putting a 
cherry bomb in a beer can next to my ear is going to help me."

So, the couple drove to Georgia to get a second opinion.  
The Georgia physician was about to tell them about the 
procedure for a vasectomy when he noticed that
they were from Alabama.  This doctor instead told the man 
to go home and get a cherry bomb, light it and place it 
in a beer can, hold it to his ear and count to 10.

 Figuring that both learned physicians couldn't be wrong, 
the man went home, lit a cherry bomb and put it in a beer 
can.  He held the can up to his ear and began to count.  
"1, 2, 3, 4, 5 ....", at which point he paused, placed the 
beer can between his legs and resumed counting on his other
hand.....
