This old man was playing the fiddle at a barn dance. He was sitting on an old pickle barrel and his pants zipper was unzipped. While playing the family jewels fell out and were hanging down in the barrel. An old lady observed all of this and felt obligated to tell him what had taken place. She went up to him and said, "Do you know your zipper's unzipped and all of the family jewels are hanging in the pickle barrel"? The old man said, "No lady, but if you can hum it I'll play it".
