After their 11th child, an Alabama couple decided¹ that was enough little hillbillies, as they could not afford a larger bed.

The husband went to his veterinarian (of course) and told him that he and his cousin-wife didn't want to have any more children and asked what could be done.

The doctor told him that there was a procedure called a vasectomy that could fix the problem, but it was expensive.

"A less costly² alternative is to go home, get a cherry bomb, (fireworks are legal in Alabama) light it, put it in a beer can, then hold the can up to your ear and count to 10."

The Alabaman said to the doctor, "I may not be the smartest tool in the shed, but I don't see how putting a cherry bomb in a beer can and holding it next to my ear and counting to 10 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 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.
