According to the chain: "Krispy Kreme Doughnuts’ home-grown sweet treats have been enjoyed by families since 1937. This year’s doughnut harvest created a surplus of delicious treats, grown with care and picked off the vine at precisely the right moment."
In case you missed it, the harvest is an April Fools joke, but the donut giveaway is not. In case you want to fool your friends into thinking that Krispy Kreme grows their own donuts, you can find the website for the joke here: http://www.krispykreme.com/DoughnutHarvest. The site also includes a number of locations that are specifically not participating in the offer.
