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

Dear Bubba,
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,
Bubba

At 4 A.M. the next morning, FBI agents and local police showed up 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
Bubba.
