Potato Farmer

A potato farmer was getting old. His son always helped him dig up the potato patch at planting season. The farmer was too old to do it himself. This year, the son was in jail. The farmer wrote a letter to his son asking if there was any way the son could get of jail to help the farmer with digging the potato patch. The son franticlly wrote back telling the farmer not to dig the potato patch this year because that's where he had hidden the bodies! The next day, the FBI showed with shovels and dug up the potato patch in search of the bodies. They found nothing. The son wrote the farmer saying that's the only way he could think of to help him in a pinch.
