After their 11th child, a hillbilly 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 vet 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 vet,
'is to go home, get a cherry bomb, (fireworks are legal in hillbilly country) light it, put it in a beer can, then hold the can up to your ear and count to 10.'
The hillbilly said to the vet, 'I ain’t the sharpest tool in the shed, but I don't see how put’n some cherry bomb in a beer can next to my ear is go’n to help me.'
'Trust me,' said the vet.
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 continued counting on his other hand.
