Chris goes to his friend Mark and says, "I'm banging the pastor's wife and I need your help. After the service, just keep the pastor occupied for an hour ok?
Mark hesitates but wants to be a good friend. After the service, he asks the pastor all sorts of obscure religious questions. Finally, the pastor asks, "Mark, what is really going on?"
Mark confesses he was helping trying to help his friend Chris.
The pastor replies, "I thought you knew, my wife died last year. Mark, I think you better get home quick."
