The devil walk boldly into a church one Sunday morning.
Everyone fled out the nearest door in terror except for one old guy up front.
He just sat there with his arms folded.
The devil strides over and demands, "Do YOU know who I am!"
Old guy: "I know who ya are."
Devil: "Aren't you afraid of me!"
Old guy: "Naw, I ain't afraid of you."
Devil: "WHY NOT ! ! !"
Old guy: "Cause I been married to your sister for thirty-eight years."
