"Arkansas Birth Control" joke
After the birth of their 10th child, an Arkansas couple decided that enough was enough. The husband went to the doctor and told him that he and his wife didn't want any more children, and what could the doctor do to help?. The doctor smiled, told him to go home, get a cherry bomb, put it in a can, then hold the can up to his ear and count to ten.
The man relayed this story to his wife, and shaking his head in doubt said, "I may not be the smartest man in the world, but I don't see how putting a cherry bomb in a can next to my ear is going to help!"
His wife agreed, and they drove to Missouri together for a second opinion. Surprisingly enough, when they told the second doctor why they'd come, he asked them where they were from, and then told them to buy a cherry bomb, put it in a can, and for the husband to hold it next to his ear and count to ten.
Deciding that both doctors couldn't be wrong, the couple went home, lit a cherry bomb and put it in a can. The husband 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 counted on his other hand:
"6, 7, 8..."
