Holy Crap: The St. Stupid's Day Parade Roasts Religion and Money (Est. 1970s)
Founded by San Franciscan Ed Holmes in the 1970s, First Church of the Last Laugh (FCLL) hosts its annual St. Stupid's Day parade on April Fool's day in the Financial District. Join your brethren at Stations of Stupid stops at the Federal Reserve Bank, where supplicants bless the Fed by donating losing lottery tickets; the former Pacific Stock Exchange building for a sock exchange; and The Banker's Heart, on the corner of Kearny and California, to give thanks by showering pennies on the black granite sculpture. As the church's online FAQ explains, FCLL claims to the be world's largest church, "Because all other religions are based on fear and guilt. Before fear and guilt can work, you must have stupidity."
