I love when food-related holidays crop up -- more likely than not, they mean we can indulge in some free victuals during the workday.

In celebration of National Donut Day, tomorrow Krispy Kreme will be offering one free doughnut to anyone who walks in the door. No purchase is necessary to take part in the promotion.

Elsewhere, Dunkin Donuts is offering a free donut with a beverage purchase. LaMar's Donuts also is advertising free treats, and Tim Hortons is giving away doughnuts to those with Facebook coupons.

Entenmann's will mark the holiday by unveiling the "largest box of Entenmann's Donuts ever created," along with a $25,000 donation to The Salvation Army. Free coffee and doughnuts will be available in New York's Madison Square Park.

National Donut Day dates back to 1938, when it was started by The Salvation Army to honor women who served doughnuts to soldiers during World War I. It occurs on the first Friday in June each year.

I suggest you bring sunglasses and a wig and try to snag as many freebies as you can!
