It's a bird... it's a plane... it's... free donuts!

Buy a dozen Krispy Kreme donuts Tuesday-- more importantly known as National Super Hero Day-- and you'll get another 12 original glazed donuts, free of charge. explains: "The League of Extraordinary Doughnuts assembled for one crucial mission: to bring joy to people across the world. Using their sweet set of superpowers, they deliver doughnuts to anyone in need of a smile."

The Penn Station location (2 Penn Plaza, Amtrak Level) is participating, and, better yet, you can take a photo with your personal hero (humans, pets, figurines all apply) at a Krispy Kreme shop or with a Krispy Kreme product with #SuperheroSelfie to be entered for a chance to win free doughnuts for life... superpower to eat endless carbs and keep your bikini body not included.
