After having their eleventh child, a Tennessee couple named LeRoy and Sarah decided that they couldn't hold any more kids in their trailer. So LeRoy 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 LeRoy 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 ten.

LeRoy later said to Sarah, "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 Kentucky to get a second opinion.

The Kentucky physician was just about to tell them about the procedure for a vasectomy when he noticed they were from Tennessee. The Kentucky doctor instead told the man to go home and get a cherry bomb, light it, place it in a beer can, hold it up to his ear and count to ten.

Figuring that both doctors couldn't be wrong, LeRoy 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.
