The Prisoner And His Wife

A prisoner in jail recieves a letter from his wife:

"Dear Husband,
I have decided to plant some lettuce in the back yard. When is the best time to plant it?"

The prisoner, knowing that the prison guards read all mail, wrote back to his wife:

"Dear Wife,
Whatever you do, do not touch the back garden. That is where I hid all my stolen money."

A week later, the prisoner recieved another letter from his wife:

"Dear Husband,
You won't believe happened: some men came with shovels and dug up the whole back yard!"

The prisoner replied:

"Dear Wife,
Now is the best time to plant the lettuce."
