An old man who lives on a farm, writes to his son in prison. "I can't grow potatoes this year. I'm too old to be digging up the field." Soon he gets a letter back from his son. "You can't dig in the field, that's where I buried the bodies!" The next morning, the police came out. They dug up the entire field but found nothing. Soon the farmer gets another letter from his son. "Now you can grow potatoes, dad. It was the best I could do from here."
