Today is The Day of the Dude -- the anniversay of the release of The Big Lebowski.
From this article (http://www.vocativ.com/culture/religion/anniversary-big-lebowski-12-que…), here is a brief description of the event and the importance of it for Dudeists.
The Day of the Dude is especially “high” because it marks the birth of our sacred text, the film The Big Lebowski. Generally we ask that people observe the day by doing something relaxed and convivial. Most people get together with friends and go bowling or drink White Russians.
Clearly off-topic, but being on-topic is not really something the Dude worries about.
