Today is Mad Hatter Day! So let us celebrate the character we have all come to know and love. So act crazy and have a Mad Hatter tea party if you would like. Or make a hat. Or just wear a crazy hat!
And just a little tidbit of trivia: The term mad hatter doesn't have a definite origin. It is thought to refer to the fact that hatters used to use mercury in the making of felt used in hats which led to nervous system problems causing hatters to tremble and appear insane. Thus mercury poisoning was also called 'Mad Hatter's Disease'.
