To superstitious Americans, Friday the 13th is known as the unluckiest day of the year. People will be on guard to ensure that they don’t break a mirror, spill the salt shaker, walk under a ladder, or cross the path of a black cat. But Wayback Burgers, serving delicious, fresh, never-frozen burgers, hand-dipped milkshakes, and more amidst an atmosphere reminiscent of a hometown burger joint, wants to transform the famously unlucky day into the luckiest day of the year. To celebrate the newfound luck of Friday the 13th, burger lovers with any variation of “Luck” in their names, first, middle, or last, will receive a free Wayback Classic cheeseburger.

According to Whitepages.com, there are approximately 6,859 people in the United States with the last name “Luck” and another 2,737 “Lucky” ducks, but that doesn’t count all of the variations. As long as burger lovers have a little bit of “luck” in their name, they are welcome to chow down on a Wayback Classic: two 100-percent fresh, never-frozen beef patties, two slices of American cheese, topped “Our Way” with ketchup, mustard, onions, pickles, and lettuce, served on the house. This offer is valid at participating Wayback Burgers locations nationwide on Friday, May 13.  

“At Wayback Burgers, we understand the superstitious nature that surrounds Friday the 13th, so our team came up with a plan to turn this unlucky day into a lucky one,” says John Eucalitto, president of Wayback Burgers. “We welcome all guests—lucky or not—to join us for a burger on May 13, because any day we can bite into a great burger is a lucky day in our books.”
