Two people*, who are both my friends on Facebook but who live 1,400 miles apart and have never met and probably never will, both posted a link to this video. I took that to be a sign that I should spread the video a bit further.
* Fred was in my Jeopardy! audition group; unlike me, he appeared on the show, was a three-day champion, and won, iirc, $60,000+. Dorothy is a [former?] knitblogger who lives in the Pacific NW. Hi, Fred! Hi, Dorothy!
