After having their 11th child, the couple from the small local village decided that was enough so the husband went to his doctor and told him that he and his wife 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 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, I don't want to go deaf!"
So, the couple drove to another town to get a second opinion. The new physician was just about to tell them about the procedure for a vasectomy when he noticed that they were from the small local village.
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 which point he paused, placed the beer can between his legs and resumed counting on his other hand.
