I know, I know…. now you want the question. (Some of you have been watching “Jeopardy” too long!)

WordPress has a nifty tool that tells us how people find our site.  Believe it or not, someone was searching for the plural of “thermos.”

Back, when dinosaurs roamed the earth, I wrote an article joking about the plural of ‘thermos.’  I said I thought it should be ‘thermi.’

Now I can take a rest! Whew! This ice is cold!!
