这其实是个外语冷笑话，但实在好好笑啊。

After having their 11th child, an Arkansas couple decided that was enough, as they could not afford a larger bed. So, the husband went to his veterinarian and told him that he and his 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, but that it was expensive. A less costly alternative, said the doctor, was to go home, get a cherry bomb (fireworks are legal in Arkansas), light it, put it in a beer can, then hold the can up to his ear and count to 10.
　　
　　The Arkansan said to the doctor, "I may not be the smartest man in the world, but I don’t see how putting a cherry bomb in a beer can next to my ear is going to help me."
　　
　　"Trust me," said the doctor.
　　
　　So, 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.
　　
　　This procedure also works in Mississippi and Alabama.
