Happy National Cheeseburger Day! Yes, there really is a day for everything.

But a day for everything means there’s a deal for everything, and so some of your favorite burger spots are serving up discounts – and free burgers – to celebrate.

We’re not sure when this day was invented or why it falls on this day in particular, but we do know these random facts about cheeseburgers:

The cheeseburger was likely invented by a teenager

If you’re going to be devouring a juicy burger today, you may have Lionel Clark Sternberger to thank.

Legend has it that Sternberger invented the cheeseburger sometime in the mid-1920’s, forever altering the course of human history.

Mr Sternberger – can we call you “Berger” for short? – was a teenage short-order cook at a restaurant called The Rite Spot in Pasadena, California.

One day, Sternberger slapped some cheese on top of a patty and America was never the same.

Americans have a favorite cheese for their burger

Forget the fancy stuff. Unsurprisingly, Americans prefer American cheese on their burger. According to the 2019 Burger Consumer Trend Report, 70% of Americans prefer the processed stuff over cheddar cheese.

Mallie’s Sports Grill & Bar owner Steven Mallie spent four years figuring out how to execute making a 1,794 pound cheeseburger. And in 2017, he did it. The burger earned a Guinness World Record and is on the menu, but it will cost you a whopping $10,000 to try.
