"Murphy showed up at Mass one Sunday" joke

Murphy showed up at Mass one Sunday and the priest almost fell down when he saw him. 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, "I got to be honest with you Father, a while
back, I misplaced me hat and I really, really love that hat.
I know that Mc Glynn had a hat just like me hat, and I knew
that McGlynn come to church every Sunday.
I also knew that McGlynn had to take off his hat during
Mass and I figured he would leave it in the back of church.
So, I was going to leave after Communion and steal McGlynn's hat."
The priest said, "Well, Murphy, I notice that 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; "After I talked
about 'Thou Shalt Not Steal' you decided you would rather
do without your hat than burn in Hell, right?"
Murphy shook his head and said, "No, Father, after you
talked about 'Thou Shalt Not Commit Adultery' I remembered where I left me hat."
