"Redneck Birth Control" joke
After having their 11th child, a Kentucky couple decided that was enough(they could not afford a larger double wide).
So, the husband 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 him that there was a procedure called a vasectomy that could fix the problem. The doctor instructed him to go home, get a cherry bomb (fireworks are legal in Kentucky), light it, put it in a beer can, then hold the can up to his ear and count to 10.
The Kentuckian said to the doctor, "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 Ohio to get a second opinion.
The Ohio physician was just about to tell them about the procedure for a vasectomy when he noticed that they were from Kentucky. This doctor instead told the man to go home and get a cherry bomb, light it, place it in a beer can, hold it to his ear and count to 10.
Figuring that both learned physicians couldn't be wrong, 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....
