The Big Mac jingle introduced the phrase “Two all-beef patties” in its famous product description.
The jingle promoted the Big Mac by listing its ingredients in a memorable sequence: two all-beef patties, special sauce, lettuce, cheese, pickles, onions, and a sesame-seed bun. The compact wording turned the sandwich's construction into a piece of McDonald's brand language.
McDonald's used the ingredient rhyme in advertising beginning in the 1970s. Its success made the Big Mac easier to remember and gave customers a verbal way to identify the product. The phrase became one of the best-known examples of food advertising copy.
The wording is sometimes attributed to the general McDonald's brand rather than to a specific product campaign. However, the jingle was specifically associated with the Big Mac. It should also not be confused with “You Deserve a Break Today,” which promoted the wider restaurant brand rather than listing a burger's ingredients.
