Picture it: rural area, Sunday morning, church is packed. The devil decides to pay a visit. The doors burst open, and a roiling black cloud rolls in with the devil in its midst. People jump out of the pews and run outdoors, screaming - all except for two. One is the Pastor, the other is an elderly farmer.
Satan is a bit perplexed. He points to the Pastor and says, "You! I can understand why you didn't run away, you are in your Lord's house, you preach against me everyday and you aren't afraid of me. But YOU (points to the farmer), why didn't you run out scared like everyone else?"
The farmer crosses one leg over the other and drawls, "Why, I'm surprised you don't recognize me...I've been married to your sister for 36 years!"
