After the church service on Sunday one man asks a friend of his, "Hey, Buddy, I have a date with someone's wife after church, uh, could ya keep the preacher man busy for at least a half hour for me?"
This man reluctantly agrees. He makes small talk with the preacher man about how nice the new paint on the reception hall looks, asks about the future plans on the building, talks about the excellent grounds keeping, and then after about twenty minutes he realizes he is running out of ideas.
He finds himself saying, "Preacher, I have a confession. I was asked to become a diversion to you by keeping you here for at least a half hour while someone I know could spend time with someone else's wife."
Preacher man asks, "What are you saying, son?"
"I am afraid your wife is having an affair, sir."
The Preacher man lays a hand on the other man's shoulder and with a smile states, "My wife died over a year ago. You better hurry home, son."
