I don't know who's in charge of picking national days but give that person a raise immediately. A corner office too! National French Fry Day is tomorrow, July 13, and there's no better reason to dive into arguably the best way to enjoy a potato on the go. Unless you're eating mashed potatoes in a cone, I guess.

McDonald's is diving right into the spirit of this holiday with a sweet deal. Via the McDonalds app, French fry lovers will be able to score a free large fries on National French Fry Day at all participating locations. No purchase necessary either. Just show up and get your fries after ordering through the app.

So now you've got the free large fries to complete the McNuggets, Big Mac (because you like to keep it classic) and apple pie meal that I'm sure we all eat and not just me.

The French fries are only going to be free on July 13th so make sure to download the app and visit your local McDonald's.
