Genius

An old man lived alone in the County. He wanted to dig his potato
garden, but it was very hard work as the ground was hard. His only son
Fred, who used to help him, was in prison. The old man wrote a letter to
his son and described his predicament:

Dear Fred,
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; 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, Fred

At 4 am 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.

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, Fred
