The baby back ribs jingle was Chili's signature TV ad song, first aired in the late 1980s as a doo-wop style spot. Its insanely catchy hook turned it into one of the most famous restaurant jingles in America, sung in bars and quoted for decades. Chili's revived it years later with a celebrity remake, and the chorus took on a second life online as a meme sound for food cravings and BBQ edits. The melody's barbershop sincerity is exactly what makes it so endlessly quotable.
