After having their 10th child, an Indiana couple decided that was enough. So 
the husband went to his doctor and told him he and his wife didn't want to 
have any more children. The doctor told him  there was a procedure called a 
vasectomy that could fix the problem. 
 
The doctor then gave the husband the following directions: go home, get a 
cherry bomb, put it in a can, then hold the can up to his ear and count to 
10. The guy from Indiana said to the doctor, "I may not be the smartest man, 
but I don't see how putting a cherry bomb in a can next to my ear is going to 
help me."
 
So the couple drove to Ohio to get a second opinion. The doctor was just 
about to tell them about the procedure for a vasectomy when he noticed they 
were from Indiana. This doctor also told the man to go home and get a cherry 
bomb, place it in a tin can, hold it next to his ear and count to 10.
 
Figuring that both doctors couldn't be wrong, the man went home, lit a cherry 
bomb and put it in a 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 can between his 
legs and resumed counting on his other hand.
