Farmer Frank had a nagging wife who made his life miserable. The only real peace that he got was when he was out in the field plowing.
One day when he was out in the field, Frank's wife brought his lunch to him. Then she stayed while he quietly ate and berated him with a constant stream of nagging and complaining. Suddenly, Frank's old mule kicked up his back legs, striking the wife in the head, and killing her instantly.
At the wake, Frank's minister noticed that when the women offered their sympathy to Frank he would nod his head up and down. But when the men came up and spoke quietly to him, he would shake his head from side to side.
When the wake was over and all the mourners had left, the minister approached Frank and asked, "Why was it that you nodded your head up and down to all the women and shook your head from side to side to all the men?"
Well, Frank replied, "The women all said how nice she looked, and her dress was so pretty, so I agreed by nodding my head up and down. The men all asked, 'Is that mule for sale!?'"
