After having their 11th child, an Louisiana couple decided that that was
 enough (they could not afford a larger double-wide trailer).  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, light it, put
 it in a beer can, then hold the can up to his ear and count to 10.  The
 Louisiana man 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 just about to tell them about the procedure for a
 vasectomy when he noticed that they were from Louisiana.  This doctor
 instead told the man to go home and get a cherry bomb, light it, 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 that
 point he paused, placed the beer can between his legs and resumed
 counting on his other hand.
