Interviewer: You were known as the rock of that set, Harry. The veteran who always hit his marks and knew every line before he even stepped out of the trailer. Did you ever feel the pressure of being the new guy, following a beloved character like McLean Stevenson’s Henry Blake?

Harry: (Laughs) Oh, every single day for the first two years, son. You have to understand my background. I was the old pro. I came from the Dragnet days where you showed up, you said your lines with a straight face, and you didn’t wiggle your ears or miss a beat.

I felt I had a very serious reputation to uphold. I felt I had to be the grown-up in the room because, Lord knows, Alan Alda and Mike Farrell and Jamie Farr weren’t going to do it. They were like a pack of unruly puppies most of the time, always looking for a way to turn a serious medical scene into a three-ring circus.

But there was this one night. I think it was late in our second season together, so we’re talking 1976 or 1977. We were filming an episode called ‘The General’s Practitioner.’ It was a long, grueling day on the Fox ranch. We had started the engine at six in the morning and it was now well past midnight.

We were all exhausted, the kind of deep, soul-crushing tired where your bones actually ache and your brain starts to feel like a bowl of warm, lumpy oatmeal. We were filming in the Swamp. It was cramped, incredibly hot under those massive studio lights, and it smelled like old canvas, dust, and very stale coffee.

The scene was written to be very tense. I had to deliver this stern, military lecture to BJ and Hawkeye about their lack of administrative discipline in the compound. It was one of those classic Potter speeches, full of ‘mule muffins’ and ‘horse hockey’ and all those wonderful, grumpy ‘Potter-isms’ the writers loved to give me.

The script had this particularly complex sentence. It was a real tongue-twister about the administrative efficiency and the logistical requirements of the 4077th compared to the rest of the Eighth Army on the Korean Peninsula. I had been sweating over it in my trailer all afternoon.

I wanted to nail it in one take so we could all just go home and sleep. The director called for quiet. The red light went on. The boom mic swung over my head like a heavy pendulum. I looked over at Mike Farrell. He had this very serious, focused expression on his face, playing the part of the chastened subordinate perfectly.

I cleared my throat. I felt the words lining up in my head like soldiers on parade. I was ready to be the Colonel. I was ready to be the anchor.

And that’s when it happened.

Harry: I opened my mouth to say the phrase ‘administrative efficiency,’ but my brain and my tongue had a complete falling out right there on camera. What actually came out was something that sounded like a vacuum cleaner swallowing a wet sock.

It was this bizarre, high-pitched, strangled warble that ended in a sound that I can only describe as a frantic, honking goose. It wasn’t even a word. It was a noise that no human being should be able to make accidentally.

The room went dead silent for exactly one second. You could actually hear the crickets outside the soundstage in the California night. I just stood there, my mouth still hanging open, frozen in the middle of this supposedly terrifying military reprimand.

My finger was still pointed in the air for emphasis. I looked at Mike Farrell. I knew as soon as I made eye contact that I was finished. Mike didn’t move an inch, but I saw his eyes start to water almost instantly.

Then, his left eyebrow began to twitch in this frantic little rhythm. It was like a tiny signal that the dam was about to burst. He made this small, suppressed ‘ppfft’ sound, trying so hard to hold it in that his face turned a shade of deep purple I’ve never seen on a human before.

That was the end of it for me. I started laughing so hard I actually doubled over and hit my head on the edge of the wooden cot in the Swamp. I didn’t even feel the pain because I couldn’t get any air into my lungs.

I was gasping for air, pointing at the script on the table as if it were the script’s fault that I had suddenly lost the ability to speak the English language. Then the crew went. Our director, who had been grumbling about the schedule and the budget for hours, just dropped his headset on the floor and put his face in his hands.

He wasn’t crying because he was upset; his whole body was vibrating. He was laughing so hard he couldn’t even find the breath to call for a ‘cut.’ He just sat there in his chair, shaking like a leaf. The camera operator was the best part, though.

This was a big, burly guy named Joe who had seen everything Hollywood could throw at him over thirty years. He actually let go of the camera handles entirely. The frame just started drifting slowly toward the floor, catching the bottom of my boots as I literally slid off the chair and onto the dirt floor.

If you ever see the raw footage from that night, you can see the camera shaking violently because Joe was sobbing with laughter. He had to lean against the tripod just to stay upright. It was a total, beautiful collapse of professional decorum.

For ten solid minutes, nobody in that tent could speak a coherent word. Every time I tried to sit back up and apologize, I’d think about the sound I had made—that pathetic, accidental ‘honk’—and I’d start the whole cycle all over again.

Alan Alda wandered in from the craft services table to see what all the commotion was. He took one look at me on the floor and Mike purple in the face, and he just started laughing because the energy in the room was so thick and infectious.

That was the moment I realized I wasn’t the ‘new guy’ or the ‘stern veteran’ anymore. I was one of them. I was part of the chaos. We eventually got the take, but it took us another hour because every time I got to that specific word in the script, Mike would make a tiny, almost silent clicking noise with his tongue, and I’d lose it again.

We probably spent thousands of dollars in wasted film and crew overtime that night just because I couldn’t say the word ‘efficiency.’ But looking back, that was the night we really became a unit. It was the night the ‘Colonel’ finally became ‘Harry’ to the rest of the cast.

They saw that the old pro from the black-and-white era could fall apart just as easily as the rest of them. The crew never let me forget it, either. They were ruthless. For the next three weeks, whenever I walked onto the set in the morning, the guys in the sound department would play a recording of a goose honking over the studio loudspeakers.

It became this legendary piece of set history that we’d talk about at every wrap party and every reunion for the next thirty years. There’s something about the pressure of a show like MAS*H—the heavy themes of war, the blood on the scrubs, the long hours—that makes those moments of pure, accidental idiocy so vital.

You need that release. You need to know that even the guy in charge, the man who is supposed to be the moral center of the camp, can turn into a honking bird at two in the morning. It taught me that the best way to lead a group isn’t by being perfect or being the ‘big actor.’

It’s by being the first one to laugh when you’re not. I’ve done a lot of work in my career, from film noir to Westerns, but I don’t think I’ve ever felt more at home or more accepted than I did on that floor, gasping for air while my friends laughed along with me.

That little ‘honk’ was probably the most important line I ever delivered in my eleven years on that show. It broke the ice, it broke the tension, and it finally broke me into the family. I wouldn’t trade that mistake for a thousand perfect takes.

It’s funny how the things that feel like professional disasters in the moment become the stories you cherish the most when the lights go down and the cameras stop rolling for the last time.

Does a specific memory from your favorite TV show still make you laugh out loud years later?
