You know, people always ask me if playing a character as tightly wound as Frank Burns was exhausting. I always tell them the same thing: it was an absolute joy, mostly because the guys around me made it impossible to stay serious for long.

I was recently sitting down with a production crew for a retrospective documentary, looking through these gorgeous, high-contrast black-and-white promotional photos from the early seasons. One shot showed the entire operating room crew crowded around a single table, all of us looking intensely serious.

Seeing that picture instantly brought me back to a scorching Tuesday afternoon in Malibu. We were filming a heavy, dramatic influx of casualties for an episode in season three. The swamp was hot, but the operating room set was a simulated pressure cooker.

The directors always wanted those O.R. scenes to feel incredibly authentic, which meant we had real medical advisors on set, blood pumps working overtime, and a heavy layer of condensed sweat sprayed onto our brows before every single take.

On this particular day, we had been resets for hours. Everyone was exhausted, our feet were aching in those canvas boots, and the tension in the room was palpable.

Alan Alda was at the primary table, delivering a fast-paced, highly technical monologue about a torn artery while working with actual surgical instruments.

My job as Frank was to stand directly across from him, looking thoroughly incompetent yet deeply arrogant, waiting for my cue to inject a completely different, wrong-headed medical opinion into the crossfire.

The cameras were rolling, capturing a tight close-up on Alan’s face as he worked with intense focus. The background extras were moving perfectly, the lighting was hitting the artificial smoke just right, and the director was finally getting the flawless dramatic take he had been chasing since breakfast.

Alan finished his complex technical line, paused with perfect dramatic timing, and looked up over his mask straight at me to deliver his final prompt.

I opened my mouth, fully prepared to bark out Frank’s condescending retort exactly as it was written in the script.

And that’s when it happened.

Instead of the crisp, military-grade medical jargon that was supposed to come out of my mouth, my brain completely misfired under the heat of the studio lights. I looked Alan dead in the eye, raised my surgical scalpel with utmost authority, and confidently demanded a completely fictional piece of hardware that belonged in a hardware store rather than a mobile army surgical hospital.

I think the exact words were, “Nurse, hand me the socket wrench, and let us bypass the carburetor.”

For a split second, the entire room hung in absolute, stunned silence. You could have heard a pin drop on the sterile linoleum floor.

Alan just stared at me over the top of his surgical mask, his eyes blinking slowly as his brain tried to process whether the script had suddenly been rewritten by a mechanic.

Then, the dam broke.

Alan’s shoulders started hitched upward, and this muffled, wheezing laugh escaped from behind his mask. Once Alan went, it was a total domino effect across the entire soundstage.

Wayne Rogers, who was working on a dummy torso at the adjacent table, completely lost his grip on his surgical clamps. They clattered loudly against the metal tray, which only made the situation worse. Wayne buried his face directly into the fake patient’s rubber chest to hide his roaring laughter, his entire body shaking uncontrollably.

The director, who had been holding his breath near the monitors hoping to finally wrap the scene, just let out a massive, defeated sigh that quickly turned into a chuckle. He didn’t even yell cut at first; he just walked onto the set shaking his head.

The camera operators couldn’t keep the equipment steady anymore. If you look at some of the raw dailies from that era, you can actually see the frame subtly bouncing up and down because the cameramen were laughing so hard behind the viewfinders.

Loretta Swit was standing right next to me, trying her absolute best to maintain her strict Major Houlihan persona, but her face was turning a deep shade of crimson. She eventually had to turn her back completely to the camera, pretending to inspect a tray of gauze just to compose herself.

The real medical advisors we had on set were perhaps the funniest part of the whole aftermath. They were sitting in the back on folding chairs, and they were practically doubled over, telling us that if anyone ever actually asked for a socket wrench in a real operating theater, they would probably be court-martialed on the spot.

We tried to reset the scene immediately, but the corporate discipline was entirely gone for the afternoon. Every time the director called for action, Alan would look across the table at me, look down at my hands, and his eyes would start crinkling at the corners. Then I would start laughing, which would trigger Wayne, and the whole cycle would start all over again.

It took us a solid six or seven takes just to get through that single transition because nobody could look at me without thinking about automotive repair.

I remember the head writer coming down to the floor to jokingly ask if we needed to write a scene where Frank accidentally works on a Jeep instead of a soldier.

That was the true magic of working on that show. No matter how heavy the subject matter was, or how exhausting the shooting schedule became, there was always this underlying current of joy and camaraderie that kept us grounded. We took the work seriously, but we never took ourselves too seriously, and those silly, human blunders were the glue that held us together for eleven years.

It is funny how a tiny mental hiccup from decades ago can still make me laugh out loud in an empty room just by looking at an old photograph.
