It's Sunday morning service at the neighborhood church.  All of a sudden, the front doors swing open with a big bolt of thunder and the Devil descends upon the congregation.  Everyone starts screaming and running away.  All, except for a little, old man, who sits in his pew as if nothing is happening.

The devil walks over to him and asks:

"Old Man, are you blind or something?"

"Nope, I can see just fine", says the old man.

"Well, do you know who I am?" the devil asks.

"Yup, I sure do", says the old man.

"Then why aren't you afraid and running away like the rest of them?"

"You don't scare me!" continues the old man.  "I've been married to your sister for the last 50 years!"
