If you invested in shares of Krispy Kreme stock 5 years ago, you've lost 90% of your money. But don't worry, they'll make it up to you. Today is National Doughnut Day (I know because Krispy Kreme says it is and they would never lie, except perhaps about accounting) and, to celebrate, Krispy Kreme locations are giving away free donuts. All you have to do is show up.

The downside is that the lines will probably be long, and it might not be worth your time.
