A preacher became frustrated that a large part of his congregation was going water skiing on Sunday rather than coming to church, so he told his wife, "This coming Sunday, I'm going to preach about the evils of water skiing on Sunday."
"What?" she exclaimed. "That's a silly thing to preach about."
"I don't think so," he said. "It's a problem we need to address."
The next Sunday as they were driving to church, the wife asked her preacher husband somewhat warily about the day's sermon topic.
As I told you," he said, "I'm going to preach about the evils of water skiing on Sundays."
"That's idiotic!" the wife retorted. "First of all, it's a dumb topic for a sermon, and second, the people who need to hear it most won't be in church. Why don't you preach about sex or something most people are interested in?"
"No. The Lord wants me to preach about the evils of water skiing on Sundays, and that's what I'm preaching about," he said firmly.
His wife said, "Well, I'm not going to sit through a boring sermon like that. I'm staying in the car. You can tell the congregation I'm sick or something." And she stayed in the car.
As the preacher walked from the car to his study at the church, he got to thinking that perhaps his wife had a valid point, so he changed his mind and gave a brilliant extemporaneous sermon on the proper role of sex in modern society.
When the service was over, one of the parishioners stopped by the preacher's car and remarked to the pastor's wife, "I'm sorry you're not feeling well this morning. "Your husband gave the finest sermon today that he's ever given since coming to this parish."
"Hmmmpf. I don't know why he thinks he's such an expert on the subject," his wife snapped. "He's only tried it twice, and he fell off both times."
