This is perhaps the most intrinsically interesting piece I have seen on your channel in some time -- and I note that many of your pieces are thoughtful and worth remembering.  (I have made a great number of referrals to your piece about life vs. risk at Pulpit Rock, which is a fine summary that is useful for many discussions in the classroom.)  But this little bit of history is inherently fascinating, and until I saw the piping screen saver, I had forgotten the teapot.  Thank you!
