Sam goes to his friend Mike and says, "I'm sleeping with the minister's wife. Can you hold him in church for an hour after the service for me?"
Mike doesn't like it, but being a friend he agrees.
After the services, Mike starts talking to the minister, asking him all sorts of stupid questions, just to keep him occupied.
Finally the minister gets annoyed and asks Mike what he's really up to.
Mike, feeling guilty, finally confesses to the minister.
"My friend is sleeping with your wife right now,
so he asked me to keep you occupied."
The minister smiles,puts a brotherly hand on Mike's shoulder and says,
"You better hurry home. My wife died a year ago."
