An old man lived alone in Ireland.
He wanted to dig his potato garden, but it was very hard work. His only son, who would have helped him, was in prison for bank robbery.
The old man wrote a letter to his son and mentioned his predicament. Shortly, he received this reply: "For HEAVEN'S SAKE, Dad, don't dig up that garden. That's where I buried the money!"
At 4 A.M. the next morning, a dozen policemen showed up and dug up the entire garden, without finding any money.
Confused, the old man wrote another note to his son telling him what happened, and asking him what to do next. His son's reply was: "Now plant your potatoes, Dad. It's the best I could do from here."
