THINK OUT OF THE BOX

An old man wanted to plant a tomato garden, but it was difficult work, as the ground was hard.

His only son, Vincent, who used to help him, was in prison, and so the old man wrote a letter to his son:
Dear Vincent,
I am feeling sad because I won't be able to plant my tomato garden this year. I'm too old already.
I know if you were here,  you would happily dig the plot for me, like in the old days.
Love,
Papa

A few days later, he received a letter from his son.
Dear Papa,
Don't dig up that garden. That's where the bodies are buried.
Love, Vinnie

At 4 am the next morning, FBI agents and police arrived and dug up the entire area without finding any bodies.
They apologised to the old man and left.

That day, he received another letter from his son:
Dear Papa,
Go ahead and plant the tomatoes now. That's the best I could do under the circumstances.
Love, Vinnie
