The visitor to church

One bright, beautiful Sunday morning, everyone in the tiny town of Johnstown got up early and went to the local church.  Before the services started, the townspeople were sitting in their pews and talking about their lives, their families, etc.  Suddenly, Satan appeared at the front of the church.  Everyone started screaming and running for the front entrance, trampling each other in a frantic effort to get away from evil incarnate.  Soon everyone was evacuated from the Church except for one elderly gentleman who sat calmly in his pew, not moving...seemingly oblivious to the fact that God's ultimate enemy was in his presence.

How this confused Satan a bit, so he walked up to the man and said, "Don't you know who I am?" The man replied, "Yep, sure do."

Satan asked, "Aren't you afraid of me?" "Nope, sure ain't", said the man.

Satan was a little perturbed at this and queried, "Why aren't you afraid of me?"

The man calmly replied, "Been married to your sister for over 48 years."
