Potato garden needs to be spaded

An old man lived alone in Idaho. He wanted to spade his potato
garden, but it was very hard work. His only son, who used to
help him, was in prison. The old man wrote a letter to his son
and described his predicament.

"Dear son, I am feeling pretty bad because it looks like I won't
be able to plant my potato 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.
Love Dad."

A few days later he received a letter from his son.

"Dear Dad, for heaven's sake, Dad, don't dig up that garden,
that's where I buried the BODIES. Love son."

At 4 am the next morning, F.B.I. agents and local police showed
up and dug up the entire garden area. But when they didn't find
any bodies, they apologized to the old man and left. Later that
same day, the old man received another letter from his son.

"Dear Dad, Go ahead and plant the potatoes now. That's the best
I could do under the circumstances. Love, Son."
