An efficiency expert concluded his lecture with a note of caution... "By the way, you don't want to try these techniques at home."
   "Why not?" asked somebody from the audience.
   "I watched my wife's routine at breakfast for years," the expert explained. "She made lots of trips between the fridge, stove, table, and cupboards, often carrying a single item at a time. One day I told her she was wasting too much time and should try carrying several things at once."
   "Did it save time?" the guy in the audience asked.
   "Actually, yes," replied the expert. "It used to take her 20 minutes to make breakfast. Now I do it in ten."
