Working in the Garden
A prisoner in the Goulburn lock-up that got done for armed robbery, received a letter from his missus:
"I have decided to plant some lettuce in the backyard. When is the best time to plant them?"
The prisoner, knowing that the prison guards read all the mail, replied in a letter:
"Dear Wife, whatever you do, DO NOT touch the back garden! You know what I hid there."
A week or so later, he received another letter from his wife:
"You wouldn't believe what happened. Some men came with shovels to the house, and dug up the whole back garden."
The prisoner wrote another letter:
"Dear wife, NOW is the best time to plant the lettuce!"
