Thursday was National French Fry Day and Friday is Bastille Day, a celebratory holiday in France, America’s oldest ally. In honor of National French Fry Day, a bunch of chains gave away free french fries.

If you missed it, you can still get free fries from McDonald’s through September 29 after downloading its app. You get an order of free medium fries Friday and every Friday through Sept. 29 at participating McDonald’s. Also, for the entire month of July you can get $1 off an order of chili cheese fries at Wienerschnitzel using this coupon.

We thought we’d celebrate both holidays by testing our readers on their knowledge of French Fries. Take this quiz and see how well you know America’s favorite golden tasty crisp comfort food.
