Reminds me of the story about the young vicar taking advice from the old vicar about how to hook people's attention at the start of a sermon, and the old vicar recommending as an example opening a sermon with the lines "Some of the best times of my life were spent in the arms of another man's wife. *dramatic pause* It was my own dear mother."

So the young vicar opts to give this a try, and stands up in front of his congregation, and says "Some of the best times of my life were spent in the arms of another man's wife." And gets a suitably shocked look for the congregation, and is flustered, and the pause hangs and hangs, and finally he says "Oh dear, I've forgotten who she was."
