"Someone stole my bicycle" complained the priest to his friend.
"In your sermon tomorrow mention the ten commandments, when you speak of the importance of Thou shalt not steal the thief will feel guilty and return it."
The next day the priest visited his friend with his bicycle.
"I΄ m so grateful. I did as you told me. When I came to Thou shalt not commit adultery I remembered where I΄ d left it."
