Happy Birthday Big Mac!

This iconic burger is turning 40 this year. Happy Birthday! “Two all-beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun.” You know how it goes. But did you know that 550 millions Big Macs are consumed in the United States annually? And that a Wisconsin man has eaten over 20,000 Big Macs since 1972. Get this…he’s actually still alive! Check out this fun birthday tribute to the Mac, complete with history of the burger and the story behind that catchy jingle.
