Efficiency
An efficiency expert concluded his lecture with a note of caution. "You don't want to try these techniques at home."
"Why not?" asked someone in the audience.
"I watched my wife's routine at breakfast for years," the expert explained. "She made lots of trips to the refrigerator, stove and table, often carrying just a single item. So I suggested, 'Honey, why don't you try carrying several things at once?'"
Another person asked, "Did it save time?"
The expert replied, "Actually, it did. It used to take her twenty minutes to get breakfast ready...and now I do it in about ten."
