David, it's a humor piece, plain and simple. Not to taken the least bit seriously. I've gotten several comments on this elsewhere that others have also challenged these studies, as well they should. But we miss the point. All the tags point to humor, and there isn't anything serious about it at all. That said, we are clueless, which is clear no matter what data points we may use to reach that conclusion, a comment which of course includes this writer!
