National Mad Hatter Day — 6 October

Have you been a little repressed or even depressed lately? If yes, grab your horns and party hats because it’s time for a very strange celebration. It’s National Mad Hatter Day on October 6 — and it’s okay to blow milk out of your nose. Celebrate with a day-long fest of silliness made especially for those who want to wear crazy top hats while walking backwards. Make Lewis Carroll proud.
