It was unhygienic, rude and gross, but Finger Lickin Good became part of our culture. The slogan is 60 years old now and it’s being replaced by a new slogan So Good. KFC tells the story that Finger Lickin Good was created by accident when franchisee David Harman appeared in the background of a U.S. TV commercial licking his digits. Afterward, a concerned viewer phoned a company manager who said, “Well, it’s finger lickin’ good.” It stuck and over time inspired music and a parody (right) among many other things.
