The slowest-growing religion in the world is Dudeism. An ancient philosophy that preaches non-preachiness, practices as little as possible, and above all, uh...lost my train of thought there. Anyway, if you'd like to find peace on earth and goodwill, man, The Church of the Latter-Day Dude will help you get started. Right after a little nap.
