 Back to Jim Birkeland. I want to remind everybody, there is a photograph of my wild cat, my wild comet, on my web page now. You can see it. Everybody's asking me to put up a photograph of comet. So there he is on the web page. And this morning's guest, Jim Birkeland, while he doesn't have a web page, we found a number of references to Jim Birkeland and earthquakes.
