"Fear of Satan" joke

The service was about to start. Everyone was in their pews chatting about their families, jobs, etc. when suddenly Satan appeared in the front of the church.

Panic ensued. In their rush to get out the back doors, people jumped over pews, trampled one another, and flew through the doors at record speeds. When the dust settled the only ones in the auditorium are Satan and one older gentleman, who did not seem at all concerned that Satan was standing directly in front of him.

Now this confused Satan a bit, so he walked up to the man and said, "Do you know who I am?"

To which the older gentleman replied, "Yup. Sure do."

Satan: "Aren't you afraid of me?"

Older gentleman: "Nope, sure ain't."

Satan was quite perturbed at this so he got right in the man's face and asked, "And would you mind telling me why not?" The older gentleman replied, "Been married to your sister for 48 years."
