An oldie but goodie.
An old man lived alone in the country. He wanted to dig up his garden and plant vegetables, but the ground was just too hard. His only son was in the state penitentiary. The old man wrote a letter to his son:
I’m feeling sad because it looks like I won’t be able to plant my garden this year. I’m just getting too old to be digging up a garden plot. If you were here, all my troubles would be over. I know you would dig the plot for me.
A few days later he received a letter from his son:
Whatever you do, don’t dig up that garden — that’s where I buried the bodies!
Early the next morning, FBI agents and local police arrived and dug up the entire area without finding any bodies. They apologized to the old man and left.
Later that day the old man received another letter from his son:
Go ahead and plant your garden now. That’s the best I could do under the circumstances.
