The host of the podcast leans in, adjusting his headphones, and asks that one question I have heard a thousand times, yet it always brings a genuine smile to my face.

He asks about the transition, the specific moment when the new guy showed up and fundamentally changed the DNA of our little mobile hospital.

I remember it like it was yesterday, even though the decades have started to blur the edges of the scripts and the specific order of the episodes we shot in the Malibu sun.

We were in the middle of a grueling season, the kind where the dust of the mountains feels like it has permanently settled into your lungs and your psyche.

McLean Stevenson had moved on, and Harry Morgan had stepped into those iconic boots as Colonel Sherman T. Potter.

Now, you have to understand that Harry was a complete pro, a veteran of the old studio system who usually knew his lines before he even arrived on the set.

He had this incredible natural gravity to him, a sense of old-school discipline that commanded immediate respect the moment he walked into the mess tent.

We were filming a scene in the briefing room, one of those moments where the comedy takes a backseat to the heavy reality of the Korean War.

It was a somber scene focused on a massive surge of casualties coming in from the front lines, and the room was thick with a self-imposed solemnity.

The lighting was dim, the air was perfectly still, and we were all physically exhausted from a 4 AM call time.

Mike Farrell and I were standing there, trying our best to look like competent, weary surgeons while our brains were essentially mush from lack of sleep.

Harry was at the head of the table, preparing to deliver a stern speech that was supposed to rally the doctors and set the tone for the entire episode.

The director called for silence, the red light went on, and Harry took a deep breath, looking every bit the formidable commander.

But just as he opened his mouth, I noticed something in his eyes—a tiny, microscopic flicker of mischief that absolutely did not belong in the 1950s.

And that’s when it happened.

Harry didn’t say a single word of his scripted dialogue; instead, he just stared directly at me for a beat too long, and then, with the most serious expression you have ever seen on a human being, he slowly let his tongue roll out of the side of his mouth.

It sounds so simple, almost childish when I say it out loud now, but in that high-pressure, exhausted environment, it was like a grenade of pure absurdity going off in the room.

Mike Farrell was the very first to go, and he didn’t just laugh; he folded completely in half, his surgical gown rustling loudly as he tried to disappear into the floor.

I tried to hold it together with everything I had, biting the inside of my cheek so hard I thought I might actually need medical attention, but the image was too much.

Seeing this dignified, legendary actor looking like a confused, panting cartoon character while playing a Colonel was the breaking point.

I let out this sharp, pathetic wheezing sound, and then the floodgates just opened for everyone in the tent.

The director, who had been desperately hoping for a quick wrap so he could finally go home to his family, just dropped his head into his hands in defeat.

The crew, who are usually the most stoic and professional people on any set, started shaking visibly.

You could see the camera literally vibrating on its mount because the operator could not stop his shoulders from heaving with silent laughter.

Harry, meanwhile, retracted his tongue with clinical precision and looked around the room with mock innocence, asking what on earth was so funny.

That, of course, made the situation ten times worse for those of us trying to recover.

We tried to reset the scene, and we really did give it our best effort to be professionals.

The assistant director shouted for everyone to get back to their marks, trying to inject some much-needed discipline back into the tent.

We took our positions, we straightened our caps, and we put on our most solemn, doctorly faces once again.

Harry started his line, “Now listen up, people,” and he got about three words into the sentence before he made the mistake of glancing at Mike.

Mike didn’t even wait for a funny face this time; he just started snorting at the mere memory of what had happened two minutes prior.

That is the thing about the giggles on a film set; they are a biological imperative that you simply cannot fight with logic or professional pride.

We must have spent forty-five minutes trying to get that one thirty-second bit of dialogue committed to film.

Every single time Harry opened his mouth to speak, we saw that tongue in our minds, even when he was keeping it perfectly still.

The director eventually had to clear the set entirely, telling everyone to go outside, breathe some fresh air, and think about something incredibly sad.

I remember standing out in the Malibu dirt with Mike, both of us leaning against a rusted Jeep, trying to talk about taxes and dental work.

We were desperately trying to discuss anything boring enough to kill the humor lingering in our systems.

But then Harry walked past us on his way to the craft services table, and he didn’t say a single word to either of us.

He just gave us that same, steely-eyed Colonel Potter glare, and for a split second, his tongue flicked out again like a lizard.

We were completely useless for the rest of the morning, and the production schedule was essentially thrown out the window.

It became a legendary moment among the cast because it effectively broke the wall of the “New Boss” persona Harry had brought with him.

Up until that point, we were all a little bit intimidated by him because he was such a giant in the industry.

But that one moment of pure, unadulterated silliness told us everything we needed to know about the man behind the character.

He wasn’t just there to play the Colonel; he was there to be one of us, to survive the long hours and the repetitive takes by finding joy in the nonsense.

I truly believe it changed the whole energy of the show for those final seasons.

We realized that if the man in charge of the camp could be that ridiculous, then it was safe for all of us to play and experiment.

I think that is why MAS*H lasted as long as it did; we weren’t just actors working a job, we were a group of people who genuinely delighted in making each other lose our minds.

Even now, when I see a clip of Harry as Potter on television, I don’t see the stern officer first.

I see the man who could bring a multi-million dollar production to a screeching halt just by being a total goofball for a second.

It is a constant reminder that even in the middle of a metaphorical war or a high-pressure career, you have to find the room to break.

If you don’t allow yourself to break a little bit, eventually, you are going to snap.

Harry taught us how to break the right way, with a sense of humor that kept us all sane.

I don’t think I ever looked at a briefing scene the same way again without checking the corner of his mouth for a sign of trouble.

It was probably the most expensive tongue-flick in the history of 1970s television, and it was worth every single penny of the overtime.

Have you ever had a moment at work where you absolutely could not stop laughing at the worst possible time?
