The studio lights were a bit too bright, and the air conditioning was doing that low-frequency hum that usually bothers a man trained in the nuances of orchestral music.

Werner Klemperer sat back in the leather chair, looking every bit the elder statesman of the arts. He wasn’t the bumbling, frantic commandant everyone remembered from Friday nights on CBS. He was elegant, poised, and possessed a voice that sounded like aged mahogany.

The interviewer, a young man who had clearly watched every episode of Hogan’s Heroes in syndication, leaned forward with a mischievous glint in his eye. He didn’t ask about the Emmy awards or Werner’s father, the great conductor Otto Klemperer.

Instead, he reached into a folder and pulled out a grainy, behind-the-scenes production still. It showed Werner in full Luftwaffe regalia, but he wasn’t looking at the camera. He was looking down at his chest with an expression of pure, unadulterated shock.

Werner chuckled, the sound deep and rhythmic. He adjusted his real glasses and peered at the photo. “Ah,” he said, his eyes twinkling. “The physics of the Third Reich. Or rather, the lack thereof.”

The fan in the front row of the small audience suddenly piped up, asking the question Werner had heard a thousand times: “How on earth did you keep that monocle in your eye while you were screaming at John Banner?”

Werner leaned forward, conspiratorially. He explained that it was all about the orbicularis oculi muscle—a bit of facial gymnastics he had perfected over hundreds of hours.

He recalled a specific Tuesday in 1967. The set was sweltering under the California sun, and they were filming a high-tension scene involving a visiting General from Berlin. This wasn’t one of the usual “silly” episodes; the guest actor was a Method player who stayed in character even during lunch.

The script called for Klink to be terrified, leaning over a map while the General barked orders. Werner had practiced a specific, frantic twitch that was supposed to make the monocle dance precariously.

But as the cameras rolled and the guest actor began his crescendo of scripted fury, Werner felt a bead of sweat roll down his temple. It was the one variable his facial muscles couldn’t account for.

He felt the glass slip. He felt the grip of the gold rim give way.

And that’s when it happened.

The monocle didn’t just fall. It didn’t drop to the floor or hit the desk with a predictable clatter.

Because of the angle of Werner’s head and the sheer velocity of the guest actor’s shouting, the glass disc took flight. It caught the studio lights like a tiny, soaring saucer and performed a perfect, shimmering arc through the air.

It bypassed the map. It bypassed the desk. It flew directly toward the guest actor, who was mid-sentence, his mouth open in a wide, theatrical roar of “Klink!”

With the kind of precision that would have made a professional athlete weep, the monocle landed squarely in the General’s mouth.

There was a split second of absolute, dead silence on Stage 13.

The guest actor’s eyes went wide. His jaw stayed open, frozen by the sudden arrival of a piece of glass and gold. He looked like a man who had just swallowed a very expensive coin.

Werner, who was a master of improvisation but also a man who took his “no-win” clause for Klink seriously, didn’t break character. At least, not at first. He stayed hunched over the map, his face contorted into the Klink grimace, waiting for the “Cut!” that wouldn’t come.

The director, Gene Reynolds, was so stunned by the sheer impossibility of the shot that he forgot to stop the tape.

Suddenly, from the shadows near the barracks set, a familiar voice boomed. It was John Banner, the legendary Sergeant Schultz. He had been watching the scene from the sidelines, waiting for his cue to enter and “see nothing.”

Banner didn’t even wait for the director. He stepped into the light, looked at the General—who was still gagging slightly on the monocle—and looked at Werner’s empty eye socket.

“Colonel,” Banner said with that unmistakable, joyful rumble, “I think your eye has gone on a diplomatic mission.”

That was the end of the professional atmosphere.

The guest actor finally spat the monocle into his hand, his face turning a shade of purple that matched his uniform trimmings. He looked at the prop, then at Werner, and then at the crew.

The camera operator, a seasoned veteran of the industry, was literally shaking. The camera began to tilt slowly toward the floor because the man holding it had collapsed into silent, rib-cracking laughter.

Bob Crane, who had been leaning against the “tunnels” entrance nearby, was doubled over, slapping his knees so hard he nearly knocked over a light stand. Richard Dawson and Robert Clary came running out of the dressing rooms, having heard the strange, choked noises coming from the stage.

“The best part,” Werner told the interviewer, wiping a tear of laughter from his eye decades later, “was the property master. This poor man, a very serious professional named Frank, came running onto the set with a bottle of alcohol and a silk cloth.”

Frank didn’t care about the comedy. He didn’t care that a miracle of physics had just occurred. He was only worried about the “sanitary condition” of the show’s most famous prop.

He marched right up to the terrifying SS General, snatched the monocle out of his hand, and began scrubbing it furiously while muttering about “saliva damage.”

The guest actor just stood there, his authority completely evaporated, watching a man polish a piece of glass that had just been inside his throat.

Werner remembered that they tried to restart the scene four times. Every time the General opened his mouth to yell “Klink,” Werner would start to twitch, and the crew would start to giggle.

Even the director eventually gave up. He called for an early lunch, realizing that the “menacing” energy required for the scene had been replaced by a spirit of pure, chaotic absurdity.

“That was the magic of that set,” Werner mused, leaning back in his interview chair. “We were playing in a very dark sandbox, historically speaking. We were refugees, many of us. We knew the real horrors of that uniform.”

He looked at the old photograph one more time and smiled.

“But in that moment, when the monocle took flight and found a new home in a General’s mouth, we weren’t actors or refugees or icons. We were just a group of friends who couldn’t believe our luck. We were being paid to be ridiculous, and for once, the universe decided to help us out.”

The audience in the studio fell silent for a moment, absorbing the warmth of the memory, before erupting into applause.

Werner Klemperer never did find a way to replicate that “trick,” though he joked that if the show had lasted another ten seasons, he might have learned how to aim the monocle at the craft services table.

It’s funny how the smallest slip-up can turn a long day of work into a story that lasts for half a century.

Do you have a favorite memory from the show that always makes you smile?
