One of my thrill-a-millisecond classes is called Business Process Improvement, in which we've started a new book called "Lean Thinking: Banish Waste in Your Corporation", so don't bother getting me it for Christmas.
Today we were discussing the history of Toyota's success, specifically its "5S" system of organization, where, magically, someone has found alliteratively appropriate English equivalents:

• Shitsuke -- sustain or self-discipline
• Seiketsu -- stabilize or standardize
• Seiso -- scrub or shine
• Seiton -- straighten or set
• Seiri -- simplify or sort

Our professor asked if anyone was familiar with the "5S" model, and Brian said he was (he had seen it during a visit to an American car company), but he added that there it had been called a "6S" model.
"What was the sixth 's'?"
"I can't remember."
(For those of you who occasionally ask, "where do you come up with this stuff?" this was the point where my mind raced into full auto. Though it always helps to get lucky.)
Then it came to him. "Oh. It was 'Safety'."
I added my two yen: "...and I believe the Japanese equivalent of that is 'shiitake'."
A pause.
Vanessa couldn't shut her big yap: "That's a mushroom."
"Exactly," I say. "It's the safe mushroom to eat."

The professor: "So you've spent some time in Japan, then?"
