Mark The Days - September 23rd

  • Welcome to September 23, when we remember Checkers, the little cocker spaniel who found himself unexpectedly involved in presidential politics, celebrate the wonderfully portable convenience of Snack Stick Day, recognize the languages that allow millions of people to communicate with their hands, and finish everything off with Great American Pot Pie Day. So today, speak with your hands, snack without utensils, raise a paw to Checkers, and approach that golden pastry crust with the seriousness it deserves. Just remember: unlike politics, when someone promises you a pot pie, you should insist they deliver it.
