I was sitting in a dimly lit studio for a podcast a few years ago, the kind of space where the muffled silence makes you feel like you’re in a confessional. The host leaned in, bypassing all the usual questions about the finale or the Emmys, and asked me something I didn’t expect. He asked, “Alan, when the cameras were off and the heat in Malibu was pushing a hundred degrees, how did you keep from losing your mind?”

That question immediately pulled me back to the 1970s, specifically to Stage 9 and the Fox Ranch. People don’t realize how grueling those Operating Room scenes were. We called them “The O.R. Marathons.” We would be in those heavy surgical gowns for fourteen hours a day under blistering lights. The floor was covered in a mixture of Karo syrup and red dye that acted as our fake blood, and after a few hours, it became incredibly sticky. Every time you moved your foot, it sounded like you were pulling tape off a box.

We were exhausted, we were sweaty, and we were trying to maintain the gravitas of a show that dealt with life and death every single week. But humans aren’t built to stay in that state of high tension for twelve hours. You start to crack. You start to look for any reason to find a bit of levity. We were notorious for pranking each other, mostly just to keep the blood flowing and the spirits up.

There was one particular Tuesday where we were filming a very long, very complicated tracking shot. It was one of those scenes where the camera moves from one table to the next, capturing the frantic energy of a “push” of wounded soldiers coming in. It required perfect timing from the actors, the extras, and the camera crew. If one person tripped or forgot a line, the whole eight-minute take was ruined.

Harry Morgan, who played Colonel Potter, was at the head of the first table. He was the pro’s pro, the veteran who rarely missed a beat. He had this incredibly serious, technical monologue about a shrapnel wound. The tension on the set was palpable. Everyone was holding their breath, hoping we’d get it in one go so we could finally break for lunch.

The camera swung around, the “blood” was glistening, and Harry reached down to make the first incision into the surgical dummy.

And that’s when it happened.

Instead of the usual foam and latex interior of the medical prop, Harry’s hand plunged directly into a cold, soggy, and very real ham and cheese sandwich that someone—we suspect a mischievous prop master or a bored co-star—had stuffed inside the dummy’s chest cavity.

The sound it made was a wet, distinctive “squish” that echoed in the silent room. Harry didn’t even look up at first. He was such a seasoned actor that his hands kept moving by instinct, but you could see the exact micro-second when his brain registered that he was currently performing a “lunch-ectomy.” His eyes went wide, and he pulled out a piece of pimento-loaf ham instead of a piece of shrapnel.

The silence lasted for maybe half a second before the entire room detonated. It wasn’t just a chuckle; it was the kind of laughter that hurts your ribs. Harry stood there, holding the ham with his surgical forceps, looking at it with this expression of pure, bewildered betrayal.

The director, who had been white-knuckled and stressed about the budget, simply put his head down on the monitor and started shaking. He didn’t even call “Cut.” He couldn’t. He was physically incapacitated by the absurdity of it. The camera operator actually had to pull his face away from the lens because his own laughter was vibrating the entire rig, making the footage look like an earthquake was hitting the 4077th.

I remember Mike Farrell and I just leaning against the “wounded soldier” next to us, gasping for air. There is something about the release of tension in a high-pressure environment that makes things ten times funnier than they would be in the real world. In that moment, we weren’t famous actors on a hit show; we were just a bunch of tired people who had reached the absolute end of our ropes and found a sandwich at the finish line.

The best part, the part that still makes me smile when I think about it, was Harry’s reaction. Most actors of his stature might have been annoyed that a long take was ruined. But Harry had this wonderful, dry wit. He didn’t drop the forceps. He just looked at the pimento-loaf, then looked at the director, and said in that perfect Colonel Potter growl, “Well, I’ll be a monkey’s uncle… I think this boy’s had a very balanced diet.”

That was the end of work for about forty-five minutes. You can’t just “reset” after something like that. Every time we tried to get back into the mindset of a war-torn hospital, someone would make a chewing sound or whisper the word “mayonnaise,” and the whole cast would collapse again. It was a domino effect of hysterics.

We eventually got the shot, of course. But the energy in the room had completely shifted. The heaviness of the day had vanished. We felt like a unit again. It’s those moments—those ridiculous, unscripted breaks in the reality of the work—that actually made the show what it was. People often ask me how we managed to make the chemistry look so real on screen. The truth is, it wasn’t just acting. It was the result of a thousand ham sandwiches.

We relied on each other to stay grounded. If the show had just been about the tragedy, we would have burned out by season three. But because we were constantly looking for the joke, even in the “blood” and the heat, we were able to keep that heart beating for eleven years.

Harry and I talked about that sandwich for decades. It became a shorthand between us. Whenever one of us was taking ourselves a bit too seriously or getting stressed about a new project, the other would just mention the “OR Special,” and the perspective would return. It was a reminder that even in the middle of a “war,” or a career, or a crisis, there is always room for a bit of nonsense.

I think that’s why people still watch the show. They can feel that underlying joy. They can feel that we actually liked being there, even when the conditions were miserable. We weren’t just colleagues; we were a family that had survived the pimento-loaf incident together.

The podcast host was laughing by the time I finished the story, and I realized that after all these years, the memory hadn’t lost its power. It’s a strange thing, isn’t it? How a ruined piece of film and a wasted take can become one of the most cherished memories of a career. It’s the imperfections that we hold onto.

We spent so much time trying to make the show “perfect,” but the things I remember most are the things that went completely wrong. The lines we forgot, the props that broke, and the moments when we were too human to keep a straight face.

That’s the secret to the longevity of the show. We weren’t playing heroes who were above the struggle. We were playing people who were struggling to stay human, and sometimes staying human means laughing at a sandwich when you’re supposed to be saving a life.

Have you ever had a moment at work where a total disaster turned into the one memory that still makes you laugh years later?
