Since today’s the first Friday in June it can mean only one thing—yes, it’s National Doughnut Day. Dreamed up in 1917 by the Salvation Army to boost troop morale during WWI, it’s a patriotic excuse to get out of the office, enjoy some fluffy carbohydrates, and understand what it’s like to be a police officer, all in the name of helping the doughnut chains—or donut chains, if you will—get lots of free publicity and attention. Dunkin’ Donuts will give you a free doughnut if you buy a drink (“While supplies last. Price and participation may vary. Plus applicable taxes.”). Krispy Kreme will give you a free one just for walking in the door and asking. Remember, on National Doughnut Day they’re calorie-free!
