Werner Klemperer sits on the small stage of a theater in 1991, the soft glow of the spotlight catching the silver in his hair.

He looks nothing like the bumbling, screeching Commandant we remember from the 1960s.

He is poised, elegant, and speaks with the refined cadence of a man who spent his youth in the world of high opera and classical music.

But then a hand goes up in the third row of the audience.

A fan leans into the microphone and asks a question that makes Werner’s entire face shift into a nostalgic grin.

“Mr. Klemperer,” the fan says, “we always saw Colonel Klink as so rigid and stoic. Was there ever a moment where John Banner just completely destroyed your composure?”

Werner laughs, a deep, melodic sound that fills the room.

He shakes his head and looks down at his hands for a long moment, the memories clearly flooding back.

He tells the audience that it was never easy to stay in character around John.

In fact, for six years, it was a daily battle of wills.

He explains that he took the role of Colonel Klink very seriously, despite the comedy.

He wanted Klink to be a real officer—vain, arrogant, and foolish—because that rigidity was the only way the jokes landed.

If Klink laughed at the absurdity, the show died.

But there was one afternoon, he says, where the Prussian mask didn’t just crack.

It disintegrated entirely.

It was a Tuesday during the filming of the fourth season on Stage 29 at Desilu-Paramount.

The scene was a standard interrogation in Klink’s office involving a very large, very elaborate tray of food.

John Banner was standing behind the door, waiting for his cue to enter as the lovable Sergeant Schultz.

I looked at him through the crack of the door right before the cameras rolled.

He had that specific, mischievous twinkle in his eye.

I knew I was in trouble the moment the director yelled action.

John didn’t just walk through the door; he launched himself into the room with more momentum than he intended.

He hit the wooden threshold of the office door with his boot, and as it happened, the floor had been freshly waxed for the scene.

Usually, John was like a ballet dancer in a bear suit—incredibly light on his feet for a man of his size.

But this time, physics took over.

His feet went up toward the ceiling and the heavy tray of gourmet props went airborne.

It wasn’t just a little spill; it was a culinary explosion that seemed to happen in slow motion.

A large, greasy prop bratwurst flew straight out of the frame and landed with a sickening, wet thud.

It didn’t hit the floor.

It hit the framed portrait of the Kaiser hanging on the office wall.

The sausage stuck there for a split second before slowly, agonizingly sliding down the glass, leaving a thick trail of grease behind.

John hit the floor hard, but instead of stopping the take or checking if he was hurt, he stayed entirely in character.

He looked up at me from the floor with those wide, innocent Schultz eyes.

He started scrambling on his hands and knees, frantically trying to grab the rolling sausages and the scattered cabbage.

“I see nothing! I see nothing!” he started shouting at the top of his lungs.

But he was saying it while trying to shove a handful of prop sauerkraut back onto a bent metal plate with his bare hands.

The crew was dead silent, which made the situation ten times worse.

You could hear the sound of thirty grown men holding their breath, trying not to ruin the audio.

I was sitting behind the desk, gripping the edges of the wood so hard my knuckles were white.

I was trying with every fiber of my being to keep my monocular in my eye.

My lip started to tremble, and my face was turning a shade of red that probably worried the lighting director.

I tried to bark a line, something about Schultz being a disgrace to the entire Luftwaffe.

But all that came out was a high-pitched, strangled squeak.

Then I made the mistake of looking over at the corner of the set.

Richard Dawson and Robert Clary were standing there, waiting for their scripted entrance.

Richard had his face buried in his hands, his shoulders shaking so violently I thought he might collapse.

Robert was actually biting his own arm to keep from screaming with laughter.

That was the end for me.

The “Klink” persona vanished instantly.

I let out a sound that I can only describe as a dying seal and fell forward onto the desk, my face buried in the blotter.

The director, Bruce Bilson, didn’t call “cut” immediately.

He was too busy laughing behind the monitor to reach the button.

He told me later he wanted to see if John would actually try to finish the scene by serving the “floor food.”

And he did.

John stood up, his uniform covered in grease and bits of cabbage, looking perfectly dignified.

He walked over to my desk, clicking his heels together with a sharp snap.

He placed the empty, messy tray directly in front of my face.

He saluted and said, “The General’s lunch is served, Commandant. Though it is perhaps a bit more ‘earthy’ than he requested.”

The entire soundstage finally erupted.

It wasn’t just a giggle; it was a roar that lasted for nearly ten minutes.

The lighting crew were doubled over in the rafters, and the script supervisor was literally crying.

We had to stop production for nearly half an hour because nobody could look at John Banner without losing it.

Every time we tried to reset the scene, I would glance at that portrait of the Kaiser.

The grease mark was still there, a perfect vertical line of sausage oil.

I would start laughing all over again, and the cycle would repeat.

John just stood there the whole time, looking perfectly content with himself.

He loved it when he could get me to break because he knew how much effort I put into being the “serious” one on set.

He made it his mission to find the one thing that would shatter my professional composure.

That day, it was a flying bratwurst and his absolute, unwavering commitment to the bit.

People think we were just actors doing a job, but there was a genuine love on that set.

John was the heart of the show.

He wasn’t just playing a character who was lovable; he was the most wonderful man I ever knew.

And that’s why it was so funny—because you couldn’t stay mad at him, even when he ruined a take.

Werner looked back at the fan in the audience and smiled warmly.

“To answer your question,” he said, “I didn’t stay serious. I was a total mess, and I loved every second of it.”

It’s a beautiful thing when the mask of a character falls away to reveal the friendship underneath.
