Yes, there's more to National Doughnut Day than just free dessert. The holiday was first created as a fundraiser for the Salvation Army in 1938.
The organization held the event to raise money during the Great Depression and to honor the "Lassies" who served doughnuts to World War I soldiers. These morale-boosting volunteers later became known among the men as "Doughnut Dollies."
The doughnut celebration caught on, and National Doughnut Day is now observed each year on the first Friday in June.
