How to be the perfect son...

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. It's the best I could do
under the circumstances.
Love, Bubba
