I was going to followup with a fork joke, but got sidetracked -- the earliest known fork utensil was dug up in Gansu China (slightly ironic), and that is much older than the knife that originated in Ginsu. The earliest known table fork was only about 1000 years ago. So, this joke really does write itself. It doesn't happen to be funny, but hey, we're talking about one of my jokes, so...
So you saying that they lost their only fork and have been using sticks ever since?
