An Irish joke from Murphy (Best read drunk)

Kelly showed up at Mass one Sunday and the priest almost fell over with joy. Kelly hadn’t been to church in years.

Enthused with Kelly’s presence, Father delivered an impassioned sermon on the Ten Commandments.
After Mass, skirts flying, Father caught up with Kelly at the church door. “Kelly, I am so glad ya decided to come to Mass, what brought ya?”

Kelly said,
“To be honest Father, a while back, I lost me hat and I really, really love that hat. I know that Murphy had a
hat just like it, and I knew that Murphy came to church every Sunday.
I figured I would sit behind him and steal his hat."

Father said, "Well, Kelly, I notice ya didn't steal Murphy's
hat. What changed your mind?"

Murphy said, “Well, after I heard your sermon on the Ten Commandments, I decided not to steal Murphy's hat after all.”

The priest gave Kelly a big smile and said;
“After I spoke about the seventh commandment, Thou Shalt Not Steal, you decided not to steal Murphy’s hat?”

Kelly shook his head and said,
“No, Father. It was when you got to the sixth commandment, Thou Shalt Not Commit Adultery.”

“I remembered where I left my hat.”
