Efficiency Expert

An efficiency expert ends his lecture on timesaving with a note of caution:   "You may not want to try these techniques at home."

"Why not?" someone from the back of the audience asks.

"I watched my wife's routine at breakfast for years,"  the expert explains.  "She made lots of trips to the refrigerator, stove, table and cabinets, often carrying just a single item at a time. 'Hon,' I suggested, 'Why don't you try carrying several things at once?'"

The voice from the back asks, "Did it save time?"

"Actually, yes," the expert says.  "It used to take her 20 minutes to get breakfast ready.  Now I do it in seven."
