They say that a preacher's wife is always his number one assistant. An example of this comes one Sunday morning after the preacher had just finished his sermon.  He went and sat down with his wife and she asked him how he thought the church service went.

The Preacher shrugged and said, "The worship was excellent, and I think the prayer and communion times went quite well, but," he continued, "I just don't think the sermon ever got off the ground."

The wife looked over at him, and before she could stop herself, she said, "Well, it sure did taxi long enough!"
