Free donuts on National Donut Day, June 5.

June 5 is National Do(ugh)nut Day, and you can enjoy free circles of fried, sugared dough courtesy of these fine folks:

• Dunkin' Donuts - Free donut, your choice of any kind, with beverage purchase
• Krispy Kreme - Free donut, your choice of any kind, no purchase necessary
• Mighty-O Donuts - Free organic mini-donuts, one per customer
• Apparently Southwest Airlines, bizarrely, celebrated NDD '08 by making a "donut tour" and handing out packages of donuts at a few airports, but no word on whether anything is planned for '09

Stay tuned for more donut day updates!
