Prison isn’t usually a topic associated with humour. It’s a serious subject, and for many people, a difficult one.

But sometimes, comedy finds its way into even the most unlikely settings. Wordplay, misunderstandings and clever punchlines can take the edge off heavier themes – without making light of real-life hardship.

“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!”
