Today (January 15) is National Hat Day.

Arby’s, whose logo happens to be a giant hat, is hoping to make the ten-gallon hat part of American history.

To that end, the chain has begun a petition to make the ten-gallon hat the “first and only official national hat.”

Oh…and they’re also offering a coupon for half off a Chocolate Molten Lava Cake.
