Recently, when I went to McDonald's, I saw on the menu that you could have an order of six, nine or twelve Chicken McNuggets. I asked for a half-dozen nuggets. We don't have half-dozen nuggets," said the teenager at the counter. "You don't?" I asked. "We only have six, nine, or twelve," was the reply. "So I can't order a half-dozen nuggets, but I can order six?" "That's right." So I shook my head and ordered six McNuggets.
