I was sitting in a dimly lit studio for a retrospective documentary on the legacy of MAS*H, and the interviewer leaned in with a question that I’ve heard many times, yet it always brings a smile to my face.

They wanted to know about the transition, about what it was like for a classically trained actor like myself to step into a well-oiled machine that had already been running for five years.

I told them that when I first arrived to play Charles Emerson Winchester III, I was determined to be the ultimate professional.

I saw myself as a serious actor entering a serious comedy, and I wanted to ensure that Winchester’s pomposity was grounded in a real sense of superiority.

But as anyone who worked on that show will tell you, the set of the 4077th was not a place where self-importance survived for very long.

The cast was a family of practical jokers, led by the incomparable Harry Morgan.

Harry was our rock, our Colonel, and arguably the most disciplined man in the business.

However, he possessed a wicked, understated sense of humor that could dismantle your composure in a heartbeat.

We were filming a particularly heavy scene late in the seventh season, one of those moments in the Swamp where the air felt thick with the exhaustion of the war.

The script called for a high-stakes confrontation between Potter and Winchester.

I was supposed to be at my most indignant, defending some breach of protocol with my usual Bostonian flair.

The lighting was dimmed to simulate a late-night argument, and the crew was exhausted from a fourteen-hour day.

We all just wanted to get the shot and go home.

I remember standing there, smoothing out my robe, rehearsing my rebuttal in my head.

I looked over at Alan and Mike, who were tucked into their bunks, ready to play the weary witnesses to our clashing egos.

Harry was standing just outside the tent flap, waiting for the director to give the signal.

The silence on the soundstage was absolute.

I took a deep breath, adjusted my glasses, and waited for the Colonel to storm in and tear me a new one.

I was locked in, fully committed to the drama of the moment.

I saw the canvas flap flutter, and I steeled myself for the verbal onslaught of Sherman T. Potter.

And that’s when it happened.

Harry didn’t just walk in.

He marched into the Swamp wearing his surgical magnifying loupes—those high-powered telescopic lenses that surgeons use for delicate work—but he had them adjusted in such a way that his eyes were magnified to three times their normal size.

He looked like a giant, radioactive owl.

But he didn’t acknowledge the glasses at all.

He stood there, perfectly rigid, and delivered his first line with the utmost gravity.

“Winchester,” he barked, but as he said it, he leaned forward so that those giant, magnified eyes were only inches from my own.

The sight was so absurd, so contrary to the somber tone of the scene we had spent an hour preparing, that my brain simply stalled.

I tried to deliver my response, something about the “unmitigated gall” of the suggestion, but the words died in my throat.

I made a sound that I can only describe as a high-pitched whimper.

Then, the laughter hit me like a physical wave.

I collapsed onto my cot, burying my face in my hands, while Alan Alda and Mike Farrell absolutely lost their minds in the background.

The director, Charles S. Dubin, shouted “Cut,” but he was already laughing into his hand.

The best part was Harry’s reaction.

He stayed in character.

He didn’t crack a smile.

He just stood there with those ridiculous bug-eyes, looking around the tent as if he were deeply offended by our lack of professionalism.

He looked at the camera crew and asked, in his perfect Potter voice, “What seems to be the trouble? Is the lighting inadequate?”

That sent us into a second round of hysterics.

We spent the next ten minutes trying to pull ourselves together.

Every time I looked at Harry, I would see those lenses, and I would start wheezing all over again.

The crew was in stitches.

The camera operator had to step away from the eyepiece because he was laughing so hard he was shaking the entire rig.

We finally managed to reset, and everyone took a collective breath.

“Alright, let’s do this for real,” the director said, trying to regain control.

We went for Take Two.

The tent flap opened.

Harry walked in.

He had taken the glasses off this time.

I thought I was safe.

I looked him in the eye, ready to deliver my line.

But just as I opened my mouth, Harry let out a tiny, barely audible “Hoot” sound.

It was a callback to the owl-look from the previous take, and it was a surgical strike on my composure.

I didn’t even try to fight it.

I just walked out of the tent.

I walked right off the set and stood in the dark of the soundstage for five minutes, trying to remember how to breathe.

When I came back, the entire cast and crew were in a state of collective delirium.

It’s one of those things that only happens when you’ve been working together for years.

The humor becomes a shared language, a shorthand that bypasses the brain and goes straight to the funny bone.

We eventually got the take, but only because the director threatened to ban Harry from the mess tent if he did it again.

Even then, if you watch that specific episode closely, you can see the corners of my mouth twitching.

You can see the slight redness in my eyes from the tears of laughter.

That moment became a legendary part of our history.

It was the day the “Serious Actor” David Ogden Stiers was thoroughly and permanently broken by the “Colonel.”

Looking back, I realize those were the moments that truly mattered.

The show was about the horror of war, but the experience was about the resilience of the human spirit.

We laughed because we had to.

We laughed because the alternative was far too heavy to carry every day.

Harry Morgan taught me that the highest form of professionalism is knowing exactly when to let the light in.

I still have a pair of those surgical loupes in a drawer somewhere.

Every time I see them, I hear that little “hoot” and I’m right back in the Swamp, surrounded by my dearest friends, losing my mind in the best way possible.

It’s a reminder that even in the most serious of times, there is always room for a little bit of beautiful, chaotic nonsense.

Do you have a favorite Colonel Potter moment that always makes you smile?
