Before you go worrying about Friday the 13th, see what a great excuse for a party it is! On December 13, 1940, Chicago's Anti-Superstition Society held a Friday the 13th party at the Merchants & Manufacturers Club of Chicago. A good time was had by all. LIFE magazine was there, so there are plenty of great pictures of members breaking mirrors, spilling salt, and lighting three on a match. Link -via Metafilter
