John Banner sits back in the armchair, the soft studio lights of the 1970s talk show set reflecting off his glasses. He looks every bit the jolly, grandfatherly figure the world came to love as Sergeant Schultz. The interviewer, a young man with a wide tie, reaches into a leather portfolio and pulls out an old, glossy production still.

He hands it to John. The actor’s face softens instantly. It’s a shot from Klink’s office—Werner Klemperer is mid-shout, his monocle practically vibrating with indignation, while John stands there with that famous, wide-eyed look of feigned innocence.

John runs a thumb over the edge of the photo and let out a warm, rumbling chuckle that seems to start in his boots. He looks at the interviewer and shakes his head.

“You know,” John says, his voice a rich, melodic baritone, “people always ask me if Werner was really that stiff, that Prussian. But the truth is, the more serious he tried to be, the more dangerous it was for me. We were filming an episode in the late sixties—I can’t remember the name, they all blur together after a while—but it was a cold Tuesday morning on the Stalag 13 set.”

He leans in, as if sharing a secret with the audience.

“We had been doing this for years at that point. We were a well-oiled machine. But on this particular morning, Werner had decided that Colonel Klink was feeling particularly ‘military.’ He was snapped into that uniform so tight I thought he might pop. He was pacing back and forth in that office, clicking his heels with enough force to wake the dead.”

John laughs again, remembering the tension.

“I was supposed to be standing at attention, terrified because Hogan had smuggled something—I think it was a whole printing press—right under my nose. The script called for Werner to get right in my face, nose to nose, and scream until his face turned red. We’d done it a hundred times, but that morning, the air in the studio was heavy. We were all exhausted, and when you get that tired, everything becomes funny.”

He describes how the director, Bruce Bilson, was calling for absolute silence. The cameras started rolling. The red light went on. Werner started his approach, his boots hitting the floorboards like hammer strikes. He stopped a fraction of an inch from John’s nose.

John could see the tiny beads of sweat on Werner’s upper lip. He could see the reflection of the entire crew in that famous monocle. The silence in the room was absolute, the kind of silence that makes you want to scream just to break it.

Werner drew a massive, theatrical breath, his chest expanding against his tunic. He opened his mouth to deliver the crushing blow of dialogue that would start the scene.

And that was the exact moment the universe decided to intervene.

The sound didn’t come from Werner’s mouth, and it didn’t come from the script. It came from my own midsection.

I had skipped breakfast that morning, a rare mistake for a man of my proportions, and my stomach decided to lodge a formal protest. It wasn’t just a small growl. It was a deep, resonant, three-stage roar that sounded exactly like a Panzer tank trying to start up in the middle of a blizzard.

The sound echoed off the wood-paneled walls of Klink’s office. It was so loud that the sound mixer actually ripped his headphones off his ears in the booth.

Werner was still standing there, his mouth open, ready to scream “Schultz!” but the roar from my belly had completely drowned out his internal cue. He froze. His eyes went wide. For three seconds, he stayed in character, trying to process if an earthquake had just hit North Hollywood.

Then, he looked down at my stomach. Then he looked back up at my eyes.

The monocle didn’t just fall—it leaped. It popped out of his eye socket as if it were trying to escape the building.

I tried to keep a straight face. I really did. I squeezed my eyes shut and prayed for a sudden power outage. I tried to think of every cold winter I’d ever lived through. But I could feel the corners of my mouth twitching. I looked at Werner, and I saw that his face wasn’t red from anger anymore; it was turning a very alarming shade of purple from suppressed laughter.

“Schultz,” Werner whispered, his voice trembling. “Was that… was that an act of sabotage?”

That was it. The dam broke.

I let out a howl of laughter that probably could have been heard over at the Desilu gates. Werner collapsed into his big leather chair, clutching his sides, gasping for air. He was pointing at me, unable to speak, just making these high-pitched wheezing noises.

The director yelled “Cut!” but he was laughing too. The cameramen were leaning against their equipment, shoulders heaving. Even the extras playing the guards outside the windows were doubled over.

We tried to reset. We really tried. Gene Reynolds, our producer, came out and told us we were behind schedule and that film was expensive. We nodded like good little boys. We wiped our eyes. We straightened our caps.

We got back into position. Werner put the monocle back in. He looked at me with that stern, unforgiving glare.

“Now, Schultz,” he began, his voice steady. “I want the truth about these tunnels…”

And right on cue, as if it were a paid performer, my stomach let out a tiny, high-pitched “yip.”

Werner threw his head back and screamed. He didn’t just laugh; he became hysterical. He started throwing his arms around, shouting, “It’s talking to me! The bratwurst is giving me the coordinates!”

Bob Crane wandered onto the set from the barracks, hearing the commotion. He took one look at the two of us—two grown men in German uniforms, crying with laughter and holding onto each other for support—and he just started applauding.

“John,” Bob said, “I’ve seen you pull some stunts, but I didn’t know you’d mastered ventriloquism with your gallbladder.”

We lost forty-five minutes of production time that day. Every time we looked at each other, the cycle would start all over again. We had to eventually film my close-ups with Werner standing behind the camera, and even then, I had to look at a piece of tape on the lens because if I caught even a glimpse of his shadow, I was finished.

The crew started calling it the “Schultz Sonic Boom.” For the rest of the week, whenever I walked onto the set, the sound guys would play a recording of a lion roaring over the speakers.

It’s funny, you know? We were making a show about a very dark time in history, and we took the work seriously, but we never took ourselves seriously. If you can’t laugh at your own stomach making a fool of you in front of a German Colonel, then you’re in the wrong business.

I look at this photo now, and I don’t see the stress of the lines or the long hours. I just remember the feeling of my ribs aching from that much joy. It was a beautiful way to spend a few years, making the world laugh while we were busy laughing at ourselves.

I think that’s the secret to a long life, even if mine hasn’t been as long as I’d like. Always listen to your gut—especially if it has a sense of humor.

Do you have a memory that still makes you laugh out loud years later?
