That's not a metaphor. In 1990, Winfrey played host to live-action versions of the famous fighting terrapins, giving away an entire hour to the foursome as they sang, danced and lectured children on the importance of literacy, all to promote their Coming Out of Their Shells tour.
Footage of the Turtles' appearance was thought to be lost to history until Tumblr user Uncanny Brett White discovered a VHS copy of the episode and uploaded it to YouTube on Sunday.
During the episode, Winfrey struggled to keep a straight face as Leonardo, Donatello, Raphael and Michelangelo played their hits "Coming Out of Our Shells" and "Walk Straight," though she managed not to laugh while interviewing the Turtles about their musical aspirations.
The audience of youthful Turtles fans clamored to see the foursome fight, but the Turtles, perhaps sensing the then-common fear that they were leading children toward violence, insisted that they were peace-loving rock-and-rollers now.
Though the Turtles' newfound pacifism meant that a surprise appearance by Shredder lacked a certain dramatic climax, Winfrey seemed to enjoy the experience anyway, dropping a "Cowabunga!" for the crowd and even dancing with the Turtles, an image that deserves to be included in each of Winfrey's lifetime achievement award highlight reels for the rest of eternity.
