It is a crisp afternoon in the late 1990s, and the fluorescent lights of a hotel ballroom are humming with the quiet energy of a dedicated crowd.

Werner Klemperer sits at a long table draped in green velvet, looking every bit the sophisticated, Emmy-winning musician and actor the world had come to respect.

He is older now, his voice a melodic baritone that carries the weight of a thousand stories, yet his eyes still sparkle with that familiar, mischievous glint that once defined Colonel Wilhelm Klink.

A fan near the front of the line nervously holds up a vintage replica of the Klink monocle, asking a question that Werner has likely heard a thousand times: “How often did that thing actually fall out when you didn’t want it to?”

Werner lets out a short, dry chuckle, leaning into the microphone as the room goes silent.

He explains that the monocle was more than a prop; it was a physical extension of Klink’s ego, a brittle piece of glass that required a constant, subtle tension in his facial muscles to remain in place.

He talks about the “Prussian rigidity” he had to maintain, a mask of stern authority that was constantly being undermined by the ridiculousness of the scripts.

But then, his expression softens into a genuine, nostalgic smile.

He tells the audience that while the monocle behaved most of the time, there was one particular Tuesday during the filming of the third season that tested every ounce of his professional training.

They were filming a high-tension scene in Klink’s office.

The air on the set was thick with the smell of old dust and stage paint, and everyone was exhausted from a long week of night shoots.

In this specific scene, Klink was supposed to be at his most menacing, berating Sergeant Schultz for yet another security lapse involving the prisoners.

John Banner, the lovable giant who played Schultz, was standing at stiff attention, his large frame filling the space in front of Klink’s desk.

Werner recalls looking up at John and noticing that the Corporal looked even more nervous than usual, his eyes darting toward the door of the office.

Werner leaned in, the monocle firmly wedged in his eye, and prepared to deliver a blistering line about the Russian Front.

He noticed a strange, rhythmic clicking sound coming from somewhere near John’s midsection, but he ignored it, determined to stay in character as the cold, uncompromising Commandant.

He drew a long breath, adjusted his uniform, and prepared to scream.

That was the exact moment when the laws of physics and John Banner’s appetite finally went to war.

The silence of the set was suddenly shattered by a sound that Werner describes as a “metallic gunshot” followed by a wet, heavy thud.

It wasn’t a prop gun or a falling light.

It was the top button of John Banner’s Luftwaffe tunic, which had finally surrendered to the immense pressure of a secret, extra-large pastrami sandwich that John had smuggled onto the set from a local deli.

John had tucked the sandwich deep inside his jacket, hoping to sneak a few bites between takes because he was convinced the studio catering was “far too thin” for a man of his stature.

When John took a sharp, defensive breath to respond to Klink’s yelling, the button didn’t just fall—it launched.

The button flew across the desk and struck Werner’s monocle with the precision of a marksman, knocking the glass clean out of his eye socket.

As the monocle began its descent toward the floor, the rest of the tunic gave way, and the massive, foil-wrapped pastrami sandwich slid out from under John’s arm like a greasy torpedo.

It landed right in the center of Klink’s pristine desk, the foil bursting open to reveal layers of meat and a very large pickle.

The monocle, following a trajectory that Werner swears was guided by the gods of comedy, landed perfectly on top of the sandwich, wedging itself into the rye bread like a tiny, transparent crown.

For three seconds, there was absolute, terrifying silence.

The camera was still rolling.

The director, usually a man of quick temper, sat frozen in his chair.

John Banner, without breaking his “Schultz” persona for even a heartbeat, looked down at the sandwich, then looked at Werner’s empty eye, and finally looked at the camera.

In the most perfect, pitch-accurate “Schultz” voice imaginable, John threw his hands up and whispered, “I see nothing! I eat nothing!”

The set didn’t just break; it disintegrated.

Werner describes the reaction of the crew as a “contagious hysteria.”

Bob Crane and Richard Dawson, who were waiting just outside the door for their cue, collapsed into fits of laughter that were so loud they could be heard from the parking lot.

The lighting technician nearly fell off his ladder, and the script supervisor was laughing so hard she accidentally knocked her entire coffee over.

Werner himself, the man who prided himself on his “Prussian” discipline, couldn’t hold it together.

He slumped into Klink’s chair, burying his face in his hands as his shoulders shook with silent, violent laughter.

He says he tried to think of something sad—the state of the world, his taxes, the cold weather—but every time he looked up, he saw that monocle staring back at him from the top of a deli sandwich, and the cycle started all over again.

The director eventually gave up on the scene for the day, realizing that the “Commandant’s dignity” had been permanently compromised by a rogue piece of deli meat.

They spent the next thirty minutes just trying to clean the mustard off the top of Klink’s desk and the grease off Werner’s monocle.

Werner tells the fan convention audience that he never looked at John Banner the same way again.

From that day on, every time they had a serious scene together, Werner would spend the minutes before the cameras rolled checking John’s buttons for signs of stress.

It became a running joke among the cast; whenever a take went long, someone would inevitably ask if anyone had a sandwich hidden in their boots.

He reflects on how that moment, as ridiculous as it was, perfectly captured the spirit of the show.

They were a group of actors making light of a dark time in history, and sometimes, the best way to keep your sanity was to let the absurdity of a flying button and a pastrami sandwich take over.

The Monocle, Werner notes with a smirk, was never quite the same after being “baptized in mustard,” and to this day, he can’t pass a deli without thinking of the Great Sandwich Disaster of 1967.

He hands the replica back to the fan, his eyes crinkling at the corners, and thanks them for bringing back a memory of a man as large in spirit as he was in appetite.

It’s a reminder that even the most serious characters are usually just one loose button away from a total collapse into joy.

If you were on a set and something went that wrong, would you be the one to keep a straight face or the first one to lose it?
