(CNN) - 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.
