The tongue must be heavy indeed, because so few people can hold it. An efficiency expert concluded a lecture with a note of caution: "You don't want to try these techniques at home." "Why not?" asked someone from the back of the audience. "I watched my wife's routine at breakfast for years," the expert explained. "She made lots of trips to the refrigerator, stove, table, and cabinets, often carrying just a single item at a time. 'Honey,' I suggested, 'Why don't you try carrying several things at once?'" The person in the audience asked, "Did it save time?" The expert replied, "Actually, yes. It used to take her 20 minutes to get breakfast ready. Now I do it in seven."
