After church, the man went up to the preacher and, shook his hand and said: "I want to thank you for saving my soul today. I came to church to steal a hat, but after hearing your sermon on the Ten Commandments, I changed my mind."
"Why, that's wonderful," the preacher said: "So the commandment 'Thou shalt not steal' changed your mind, did it?"
