The devil's own.

A few minutes before the start of the church service, the
congregation were sitting in their pews talking when,
suddenly, Satan appeared at the front of the church.
Everyone started screaming and running for the exit,
trampling each other in a frantic effort to get away from
evil incarnate.

Soon the church was empty except for one elderly gentleman
who sat calmly in his pew without moving, seemingly
oblivious to the fact that God's ultimate enemy was in
his presence.

So Satan walked up to the man and said 'Do you know who I am?'

The man replied 'Yep, sure do'

'Aren't you afraid of me?' Satan asked.

'Nope, sure ain't' said the man.

'Don't you realise I can kill you with one word?' asked Satan

'Don't doubt it for a minute' returned the old man in an
even tone.

'Did you know that I can cause you profound, horrifying
AGONY for all eternity?' persisted Satan.

'Yep' was the calm reply.

'And you are still not afraid?' asked Satan.

'Nope' said the old man

More than a little perturbed, Satan asked 'Why aren't
you afraid of me?'

The man calmly replied

'Been married to your sister for 48 years!'

Good one!
I think Satan has a few sisters!
