A hillbilly woman went to the hospital to have her first child, and a year later she was back for a second child. The next year, almost like clockwork, she was back for her third child.
The hospital staff naturally began to expect her, and she was there every May to give birth.
After the 12th year she stopped coming back every spring to give birth, and the staff wondered what happened. It would be another 5 years before they would see her again, but this time for a minor injury.
When asked why she hadn’t been having any babies the past few years, she replied, “There ain’t gonna be no more, now that I figured out what was causin’ ’em.”
