“Gary, we have to talk about the transition,” the podcast host says, leaning into his microphone.

“Everyone knows the story of how McLean Stevenson left and the heart-wrenching way Henry Blake was written off.

But then came Harry Morgan.

He was a legend before he even stepped onto the MAS*H set.

Was there a specific moment when you realized that Colonel Potter wasn’t just a commanding officer, but someone who was going to change the entire energy of the show?”

Gary Burghoff sits back, a small, knowing smile tugging at the corners of his mouth.

“It’s funny you ask that,” Gary says, his voice taking on that familiar, gentle cadence.

“Because we were all actually quite intimidated by Harry at first.

He was a pro’s pro. He came from the old school of Hollywood.

He knew his lines, he knew his marks, and he didn’t miss a beat.

We were this ragtag group of younger actors who liked to cut up, and we weren’t sure if Harry was going to find us professional or just plain annoying.

We were filming an episode during his first season, and the schedule was grueling.

We had been on Stage 9 for fourteen hours.

If you’ve never been under those studio lights in full surgical gear, you can’t imagine the heat.

It was about a hundred degrees under those rafters, and we were all wearing heavy gowns, masks, and gloves.

The smell of the latex and the fake blood was starting to get to everyone.

We were doing a very intense Operating Room scene.

In the OR, the humor was usually written into the script to break the tension of the surgery, but this particular scene was meant to be straight drama.

Harry had this long, complicated medical monologue while he was ‘operating’ on a soldier.

He had to call out instruments, give orders to the nurses, and maintain this incredible gravitas.

The rest of us—Alan, Mike, myself—were just exhausted.

We were standing there, staring at the prop body, just trying to stay awake and keep our eyes focused.

Harry was delivering his lines with such precision that it was actually making us feel even more tired because we had to match his level of perfection.

The director called for another take because a light had flickered.

We all groaned, reset our positions, and waited for the slate.

Harry looked across the table at me.

His eyes were visible above his mask, and they looked perfectly serious, perfectly in character.

But then, I noticed something subtle.

There was a tiny, mischievous glint in his pupils that I hadn’t seen before.

And that’s when it happened.

Harry leaned deep into the ‘chest cavity’ of the prop patient, his brow furrowed in intense concentration as the cameras rolled.

The room was deathly silent, save for the hum of the air conditioning that wasn’t doing its job.

He reached out his hand, palm up, and we all expected him to bark out ‘hemostat’ or ‘scalpel’ in that gruff, iconic Potter voice.

Instead, Harry leaned in even closer, as if he’d discovered a medical miracle, and in a high-pitched, squeaky falsetto that sounded exactly like a Munchkin from Oz, he whispered, ‘I think I found a marble!’

The silence that followed lasted for exactly half a second.

I was the first to go.

I didn’t just laugh; I folded.

Because I was Radar, I was usually the one who had to hold the scene together, but the image of this prestigious, seventy-year-old veteran actor doing a cartoon voice while elbow-deep in a fake torso was too much.

My knees actually hit the floor.

I was leaning against the operating table, shaking so hard that the ‘patient’ started to vibrate.

Then Alan Alda caught it.

Alan has this very distinct, wheezing laugh when he really gets going.

He tried to turn away from the camera to hide it, but he ended up just doubling over and buried his face in his surgical gown.

Mike Farrell was next.

He tried to stay professional for about three seconds, but then he saw Harry’s face.

Harry hadn’t moved.

He was still standing there, hand outstretched, looking at me with those wide, innocent eyes, still in that ridiculous pose, waiting for his marble.

Within ten seconds, the entire OR was in total, unmitigated chaos.

The nurses, who were usually the most disciplined background actors we had, were literally crying behind their masks.

The director, who had been ready to wrap the scene and go home, started howling from behind the monitors.

Even the crew, the guys holding the heavy boom mics and the cameras, were visible shaking.

You could actually see the camera frame wobbling on the playback because the cameraman couldn’t control his diaphragm.

We tried to reset.

The director called for order, wiped his eyes, and yelled, ‘Action!’ again.

We all took deep breaths.

We got through the first three lines of the scene.

Harry was being perfect again.

He was the Colonel.

He was the authority figure.

But as he got to the part where he had to reach into the patient again, I made the mistake of looking at his hand.

He hadn’t even said anything yet, but the memory of that ‘marble’ comment hit me like a physical blow.

I snorted.

That was the end of that take.

Every time we tried to start over, someone would catch someone else’s eye, and the whole room would explode again.

It was an infection.

A beautiful, hilarious infection that completely erased the fourteen hours of exhaustion we’d been feeling.

Harry just stood there, looking like the cat who ate the canary.

He knew exactly what he had done.

He had purposely broken us to save our spirits.

He realized we were all hitting a wall, and he used his status as the ‘serious new guy’ to deliver a blow that would shatter the tension.

Eventually, we had to take a full twenty-minute break just to let everyone get the giggles out of their systems.

We walked outside the soundstage into the cool night air, just standing around in our bloody scrubs, laughing at nothing.

When we finally went back in and finished the scene, there was this new bond.

We weren’t the ‘young cast’ and the ‘old veteran’ anymore.

We were a unit.

Harry had shown us that he could out-prank any of us, and he did it with the kind of timing you can’t teach.

That moment became legendary on the set.

For years afterward, if things got too tense or if a scene was dragging, someone would just lean in and whisper, ‘I think I found a marble,’ and it would instantly ground us.

It taught me that even in the most serious work, if you can’t find a way to laugh at the absurdity of it all, you’re not going to make it.

Harry Morgan was the heart of that show, not because he was a stern father figure, but because he was the funniest man in the room who only used his powers when we needed them most.

I still think about that day whenever I see a marble.

It’s a reminder that sometimes, the best way to lead is to be the first one to make a fool of yourself.

It really was the best medicine we had on that set.

Have you ever had a moment where a single joke completely changed the dynamic of your workplace?
