Invent a holiday, give it a weird name, and then when the day comes around, get decked out. Talk about a place you went that no one's ever heard of. Your holiday is celebrated there and you can show your friends the timeless customs of this magical place if they'd like. Nowadays, every day is something, but no one actually celebrates it. Is it National Pancake Day? Walk around handing out pictures of pancakes, telling everyone that you’re trying to spread the word about this hidden breakfast treat but do be aware Shrive Tuesday, or Pancake Day, is celebrated widely in the UK and other Common Wealth countries.

No one will be able to tell if you're serious or not!  If you see your friend step on an ant, say, “Oh no! What have you done?! Oh, little ant, your life was so short!
