Which phrase formed the opening line of McDonald’s 1974 Big Mac advertising jingle?

“Two all-beef patties” formed the opening line of McDonald’s 1974 Big Mac advertising jingle.

The jingle began by listing the sandwich’s ingredients: “Two all-beef patties, special sauce, lettuce, cheese, pickles, onions, on a sesame seed bun.” Its compact rhythm turned the Big Mac’s construction into a memorable piece of product branding.

The advertisement became especially influential because customers could repeat the ingredient sequence from memory. Rather than relying only on the product name, McDonald’s made the sandwich’s architecture itself part of the brand message.

The phrase is sometimes confused with the full jingle or with later Big Mac slogans. The requested answer is only the opening fragment, while the complete line continues through the sauce, vegetables, cheese, and sesame seed bun.
