Billy-Bob and Peggy-Sue got married and had a baby every year or less. After having their 11th child, the couple told the doctor that they were going to stop having babies as soon as they could figure out what was causing them. The doctor suggested to Billy-Bob that he try covering the organ before they made love.
Sure enough, it wasn’t long before Peggy-Sue was pregnant again. The doctor asked Billy-Bob if he had tried covering his organ like he had suggested they do.
Billy-Bob replied, “We don’t have an organ, Doc, but I did throw a blanket over the piano.”
