A prisoner in jail received a letter from his wife:
"I have decided to plant some vegetables in the back garden. When is the best time to plant them?"
The prisoner, knowing that the prison guards read all mail, replied in a letter:
"Dear wife, whatever you do, do not touch the back garden. That is where I hid all the money."
