One bright, beautiful Sunday morning, everyone in the tiny town of
Johnstown got up early and went to the local church. Before the
service started, the townspeople were sitting in their pews and
talking about their lives, their families, etc.

Suddenly, the Devil himself appeared in front of the congregation.
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, "I been married to your sister for 48 years."
