Murphy showed up at Mass one Sunday and the priest almost fell down when he saw him, as Murphy had never been seen in church in his life.
After Mass, the priest caught Murphy and said, "Murphy, I am so glad you decided to come to Mass, what made you come?"
Murphy said, "To be honest with you Father, a while back, I misplaced me hat and I really loved that hat. I knew that McGlynn had a hat just like mine and that he comes to church every Sunday. I also knew that McGlynn had to take off his hat during Mass, so I was going to leave after Communion and steal it."
The priest said, "Well Murphy, I notice you didn't steal McGlynn's hat. What changed your mind?"
Murphy said, "Well, after I heard your sermon on the 10 commandments, I decided that I didn't need to steal McGlynn's hat."
The priest gave Murphy a big smile and said, "You mean when I talked about 'Thou Shalt Not Steal', you decided you'd rather do without your hat than burn in Hell, right?"
Murphy shook his head and said, "No Father, when you talked about 'Thou Shalt Not Commit Adultery', I remembered where I'd left it."
