A preacher was preparing his sermon for the upcoming Sunday service. He told his wife that he had decided to preach against the "sins of surfing." It seems that the members were going to the beach on Sunday instead of church, and he wanted to do something about it. His wife vigoriously protested, saying that he really should not do this, since he didn't know what he was talking about.On Sunday the preacher's wife was sick, and could not go to church with him. On his way to Church, the preacher decided that she was right, and changed the text of his sermon,deciding to preach about the "sin of illicit sex."On the following Tuesday, the preacher's wife attended her ladies church meeting. One of the ladies there commented to her that she had really enjoyed the sermon of the previous Sunday. The wife looked very surprised, and said, "Well I don't know why...I told him not to preach about it. He doesn't know anything about it, has only tried it twice, and he fell off both times."
