Efficiency Expert's Plight

I spent some time working as an efficiency expert. My credentials, you ask? I have always been extremely good at telling others how they can do things better.

As always, I concluded my lectures with a note of caution:

"You do NOT want to try these techniques at home."

"Why not?" somebody asked from the audience.

"I watched my wife's routine at breakfast for years," I explained. "She made lots of trips between the refrigerator, stove, table and cabinets, often carrying a single item at a time. One day I told her, 'Hon, why don't you try carrying several things at once?'"

"Did it save time?" the guy in the audience asked.

"Actually, yes," I replied. "It used to take her almost 20 minutes to make breakfast. Now I do it in seven."
