Launched in 1986, Mac Tonight was a character created to drive dinner business to McDonald's. Wearing 50s-style sunglasses, sitting at a white piano, and singing jingles based on the 1959 jazz hit "Mack the Knife", most popularly performed by Bobby Darin, the commercials were aimed at Baby Boomers luring them in for a bite. "When the clock strikes, half past six, babe! Time to head for, golden lights!" The campaign was originally created for Southern California McDonald's franchises by former art director Jim Benedict who worked for Los Angeles advertising firm Davis, Johnson, Mogul & Colombatto. Mac Tonight was a hit starring Doug Jones as the crescent-headed crooner voiced by Brock Walsh.

Although Mac Tonight's rise to fame included several animatronic figures of the singing man-in-the-moon and appearances in early 2000s commercials touting McDonald's After Midnight Menu, the fast food giant stopped using the jingle after Bobby Darin's son Dodd filed a lawsuit in 1989 alleging the song copied his father's singing style. While it wasn't technically one of many fast food commercials that totally flopped, and the suit seeking $100,000 in general damages and $10 million in punitive damages wasn't wholly successful, McDonald's quickly stopped airing the spot in the U.S.
Doubtless, there are many Gen Xers who still have Mac Tonight Happy Meal figurines and a lifelong earworm replaying "It's a good time for the great taste, dinner, at McDonald's, it's Mac Tonight!" But the jingle and the mascot have been relegated to the fast food giant's storied past with other characters like Ronald McDonald's pet Bernice and the roller-skating pom poms known as the Fry Kids.
