Last week we asked you to name your favorite sport yet to be indexed in the DDC. Props to Bill Murray for taking time out from what must be a punishing production schedule to wax lyrical about his first love, the fine art of chucking enormous cheeses down a steep incline and then chucking oneself after them. Many thanks also to Mark Behrens, resident social-sciences expert here at the Manor and source of much authoritative advice to the Dewey blog team, who outed himself as a big fan of the world punkin chunkin championships of Millsboro, DE: a unique event in which competitors attempt to propel pumpkins by catapult, trebuchet, or other mechanical means as far as decently possible. We'd class cheese-rolling races in 796.425 Non-track races; we'd put punkin chunkin in 796.2 Activities and games requiring equipment. All that remains now is to introduce this week's Teaser, which again isn't really a teaser per se (Leave it. -- Ed.), but a simple call for suggestions of special commemorative or celebratory days that haven't yet made it into the DDC. Saint Patrick's Day, Earth Day, Groundhog Day -- they're all indexed. But which day doesn't have the recognition it deserves? Pi Day (March 14)? Towel Day (May 25)? Talk Like A Pirate Day (September 19)? Let us know your favorite; tell us where you'd class it; and then sit back and reflect on a job exceedingly well done.
