One bright, beautiful Sunday morning, the towns people were in church, listening to the organ play. 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.
Now 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 30 years."
