Robert Clary sits comfortably in a plush velvet armchair, his posture still remarkably straight for a man who has seen as much history as he has.

We are at a small theater in North Hollywood, and the air is thick with the nostalgia of a couple hundred fans who have gathered to hear him speak about the golden age of television.

He leans toward the microphone, a familiar, mischievous glint appearing in his eyes the moment a young man in the third row asks about his relationship with John Banner.

“Ah, John,” Clary says, his voice a warm, melodic rasp. “You want to know about the legendary Sergeant Schultz? You see, people think we were just actors playing parts, but when you spend years in a mock-up of a prison camp in the middle of a California heatwave, you become something else. You become a family that survives on the currency of laughter.”

He pauses, smoothing the fabric of his jacket, and the room goes silent.

“There was this one morning in 1967. We were filming at the 40 Acres backlot in Culver City. It was one of those rare, chilly mornings where the fog hadn’t quite burned off yet, and we were all a bit cranky from the early call time. We were filming a scene in the barracks—LeBeau was supposed to be hiding a forbidden radio inside a massive tray of Napoleon pastries I had ‘borrowed’ from the kitchen.”

Clary chuckles to himself, looking at the ceiling as if he can see the rafters of Stalag 13 right above him.

“The scene was supposed to be tense. The script called for Schultz to walk in, suspicious and authoritative, nearly catching us in the act. John had been practicing his stern face all morning. He wanted to be the formidable guard for once. He really tried.”

Bob Crane and Richard Dawson were standing just out of the camera’s frame, and Clary remembers the way Dawson was whispering something into Crane’s ear right before the director shouted for silence.

“The red light went on. The set went still. The director, Bruce Bilson, called for action.”

“And that’s when it happened.”

“John Banner marched through that door like a man on a mission. He had his chest puffed out, his helmet sat perfectly level, and he looked every bit the Sergeant of the Guard. He was supposed to walk straight to the table, look at my pastries, and demand to know what was going underneath them.”

Clary leans forward, his voice dropping to a theatrical whisper.

“But right as he opened his mouth to deliver his first line, he made the mistake of looking at me. Now, you have to understand, I was wearing a chef’s hat that was slightly too large for my head. During the previous take, it had slipped forward, and a tiny dusting of white flour from the prop tray had landed right on the tip of my nose. I didn’t know it was there. Nobody had wiped it off.”

“John stopped mid-sentence. His eyes went wide. He looked at my nose, then at my eyes, then back to my nose. I could see the exact moment the professionalism left his body. His jaw started to vibrate. It wasn’t just a smile; it was a structural failure of his entire composure.”

“He tried to say, ‘LeBeau! What is the meaning of—’ but it came out as a high-pitched wheeze. He sounded like a teakettle that had just reached a boil. He clamped his mouth shut, his face turning a shade of purple I didn’t know was biologically possible. He was fighting for his life.”

“Bob Crane, seeing the opening, didn’t try to help him. Instead, Bob leaned in and whispered, ‘Is there a problem, Sergeant? You look a bit… dusty.’ That was the end. The dam didn’t just leak; it exploded.”

“John let out a roar of laughter that was so loud it actually distorted the audio recording. He doubled over, his hands on his knees, his belly shaking so hard that his belt buckle was literally clinking against his uniform buttons. It was a rhythmic, metallic sound—clack, clack, clack—that only made him laugh harder.”

“Within seconds, the entire room collapsed. Richard Dawson was leaning against the bunk beds, sliding down to the floor because he couldn’t stand up. Larry Hovis was burying his face in a pillow to keep from ruining the sound, even though the sound was already a lost cause. Even Ivan Dixon, who was usually the most disciplined of us all, was turned away from the camera with his shoulders shaking uncontrollably.”

“But the best part was the crew. I looked over the shoulder of the camera operator, and the man was weeping. He had completely let go of the camera handles to wipe his eyes. The boom mic was bobbing up and down in the frame like a fishing lure because the operator was shaking with silent giggles.”

“Bruce Bilson, the director, finally walked onto the set. He tried to look stern. He tried to remind us that we were forty minutes behind schedule and that every minute cost the studio thousands of dollars. He looked at John, who was now sitting on the edge of a bunk, gasping for air and pointing at my nose with a trembling finger.”

“Bruce looked at my nose. He looked at the flour. Then he looked at John’s helpless face. Bruce just sighed, sat down next to John, and started laughing right along with him. We lost the next twenty minutes to pure, unadulterated joy.”

“We tried to reset three times. Every time John walked through that door, he would see me, his eyes would dart to my nose, and the cycle would start all over again. He eventually had to cover his own eyes with his hands and shout, ‘I see nothing! I see nothing!’ just to get through the movement of the scene.”

“That was the day that phrase really took on its own life. It wasn’t just a line from the script anymore; it was John’s survival mechanism. He used it whenever he felt himself breaking. If he could convince himself he wasn’t seeing us, he could keep from laughing at us. We spent the rest of the season trying to make him ‘see’ things just to hear that bell-like laugh again.”

“Whenever I think of John now, I don’t think of him as the character. I think of him sitting on that bunk, his medals rattling against his chest, reminding us that even in a story about a prisoner of war camp, there was always room for a little bit of light.”

“It was the most expensive twenty minutes of laughter in the history of CBS, and I wouldn’t trade a single second of it.”

Clary leans back, the theater audience erupting into applause as he takes a small sip of water, the memory clearly warming him as much as it did the crowd.

In a world that can often feel quite heavy, isn’t it wonderful that a single smudge of flour can still make us smile decades later?

Who is the one person in your life who can make you lose your composure just by looking at you?
