In this unaired episode of Happy Days, titled “The Other Cheek,” Arthur Fonzarelli, Fonzi, the Fonz, slaps Richie Cunningham hard across the face. Void of context, we don’t know why. Richie’s jaw drops. He is in complete shock. He holds his hand against his crimsoned cheek. Richie careens out of time, out of character. He tells Arthur Fonzarelli, the Fonz, Fonzi, that he’s made a big mistake, a very big mistake, and he would be very sorry—did he know who he just slapped? You just slapped someone who was a child star—remember Mayberry, motherfucker?—and I’m gonna go on to become a major director who makes lots of films, Backdraft and Born on the Fourth of July and Apollo 13, all kinds of films, I’m gonna be the shit, and you, what are you gonna be be doing, Fonz?

When Richie—stationed somewhere between the character, Richie Cunningham, and Ron Howard, the actor playing Richie Cunningham—is done with his rant, the rest of his face has joined his cheek in turning crimson. Henry Winkler, a.k.a, the Fonz, Arthur Fonzarelli, Fonzi, is baffled, and looks around as if trying to pick up on a gag. Was he on Candid Camera? Yet everyone on set looks as baffled as he does, an awkward quiet clotting the air. One of the camera-men coughs. Ron Howard/Richie Cunningham storms off the set, muttering hotly under his breath. The Fonz, still not sure what to do, defaults to his signature move—thumbs jacked up and out, like a jazzy hitchhiker, as he mouthgrooves—Ayyyy! The live studio audience applauds. Or it canned applause? It is hard to tell the difference.
