Richard Dawson sat back in the velvet-lined chair, the soft studio lights of the late-night retrospective catchings the silver in his hair. He had that familiar, mischievous glint in his eyes, the same one that had made Newkirk such a fan favorite decades earlier. The interviewer had just asked a standard question about the most professional person on set, but a fan in the front row had interrupted, holding up a vintage, graining photograph of John Banner in full Sergeant Schultz attire.

The image showed Banner not with his usual bumbling scowl, but doubled over, his face buried in his hands. That was the trigger. Dawson looked at the photo, a slow, genuine smile spreading across his face as the years seemed to melt away. He leaned toward the microphone, his voice dropping into that rhythmic, storytelling cadence he’d perfected during his years on Family Feud.

He began by explaining that people often forgot how much of a technical grind a sitcom could be. You’re on Stage 4 at Paramount, it’s ninety degrees under the lights, and you’ve been doing the same scene for six hours. On this particular afternoon in 1968, the tension was thick. They were filming a high-stakes scene where Schultz was supposed to be under immense pressure from Klink to find a hidden “escape map” rumored to be in the barracks.

John Banner was a brilliant actor, a man who had escaped the horrors of real-world conflict and brought a profound, gentle humanity to a character that could have been a caricature. He took his craft seriously, even when the craft involved being outsmarted by a group of Allied prisoners. But everyone had a breaking point, and Bob Crane knew exactly where John’s was located.

The scene was simple: Schultz enters, Klink is watching through the window, and Schultz has to tear the barracks apart. Bob Crane had been whispering to the rest of the cast all morning, a secret plan that involved a very specific prop modification. As the cameras started rolling for the tenth take, the air in the studio was dead silent, save for the hum of the equipment.

John marched in, looking more “military” than he ever had, his brow furrowed with a rare, scripted intensity. He reached for the loose floorboard where the map was supposed to be hidden.

And that was when John’s hand made contact with the surprise.

The sound that came out of the floorboard wasn’t the crinkle of paper or the thud of wood. It was a high-pitched, long, mournful “oink” from a rubber pig that Bob Crane had squeezed into the crevice just seconds before the director yelled action.

John Banner froze. For three seconds, his face was a mask of pure, unadulterated confusion. He looked down at his hand, then back at Bob, who was standing just three feet away with the most innocent, wide-eyed expression a man could possibly muster.

Then, the dam broke.

It started as a small tremor in John’s midsection. You have to understand, when a man of John Banner’s stature started to laugh, it wasn’t a quiet affair. It was a geological event. His entire torso began to heave, and that famous “Schultz” overcoat started dancing as if it had a life of its own. He tried to stay in character, he really did. He grabbed his belt, took a deep breath, and opened his mouth to say his line about “I see nothing,” but all that came out was a wheezing, high-pitched giggle that sounded like a steam whistle.

Within seconds, the entire barracks set was in shambles. Robert Clary was literally rolling on one of the bunks, his laughter muffled by a pillow. Larry Hovis had turned his back to the camera, his shoulders shaking so hard he looked like he was having a seizure. Even Ivan Dixon, who was usually the most composed man on the planet, had to lean against the wall to keep from falling over.

The director, usually a stickler for the schedule, tried to yell “Cut,” but he couldn’t get the word out because he was too busy leaning over his script supervisor’s shoulder, laughing into a handkerchief. The camera operators had completely abandoned their posts. One of them actually had to step away from the eyepiece because his own tears were blurring the lens.

But the centerpiece of the chaos was John. He had reached the point of no return. He was weeping. Actual tears were streaming down his face, carving paths through the stage makeup. He kept trying to point at Bob Crane, but his hands were shaking too much. Bob, meanwhile, just stood there, watching his handiwork with a look of supreme satisfaction.

“You… you devil!” John finally managed to gasp out, his voice cracking. “Bob, you are a devil!”

Every time the crew tried to reset, John would catch a glimpse of that rubber pig sitting on the floorboard and start all over again. We wasted forty-five minutes of film time. Every time we got close to a take, someone would make a faint “oink” sound from the back of the room, and the explosion would happen again.

The lighting crew was laughing so hard they were accidentally swinging the barn doors on the lamps, creating a strobe effect in the barracks that only made the situation more surreal. It was the kind of laughter that hurts your ribs, the kind where you can’t breathe and you’re convinced you might actually die of joy right there on the set of a POW camp.

What made it so unforgettable wasn’t just the prank itself, but what it did for the morale of the cast. We were a family, and John was the patriarch in many ways. To see this man—who had seen so much darkness in his real life—finding that level of pure, childlike hilarity was a gift to all of us. It reminded us that we weren’t just making a TV show; we were creating a world where, for thirty minutes a week, even the “enemy” could be a source of warmth and laughter.

Eventually, we had to take a full ten-minute break. The director ordered everyone off the set to get some air. I remember walking outside into the California sunshine with John. He was still wiping his eyes, his face flushed red. He turned to me and said, “Richard, I don’t think I can ever look at a floorboard the same way again.”

We did eventually get the shot, but if you look closely at that episode, you can see that John’s eyes are still a little puffy, and there’s a slight quiver in his lip when he looks toward the floor. He was a professional to the end, but that rubber pig owned him for the rest of the day. It’s a small memory, I suppose, in the grand scheme of a long career, but it’s the one I think of whenever I miss him. It wasn’t just a blooper; it was the sound of a group of friends who truly loved what they were doing.

That’s the thing about those years—we weren’t just acting; we were living in a constant state of waiting for the next person to break. And when John Banner broke, the whole world seemed to brighten up just a little bit more.

It’s funny how the simplest things, like a squeaky toy in a wooden floor, can stay with you for fifty years, isn’t it?

What’s a moment from your own life where you simply couldn’t stop laughing, no matter how hard you tried?
