We were sitting in this dimly lit studio doing a retrospective podcast for the show’s anniversary, and the host brought up an old production still.

It was a behind-the-scenes photograph of the 4077th swamp, specifically focusing on the background elements that stayed in the camp.

Looking at that old glossy print immediately triggered a memory from season four that had completely slipped my mind for decades.

Alan Alda was sitting next to me during this interview, and the moment the host held up the picture, Alan just started shaking his head.

He looked at me and said that he still remembered the absolute chaos of that specific Tuesday afternoon on the Stage 9 set.

Gary Burghoff was famous for bringing his love of animals onto the set of MAS*H, which usually fit the character of Radar O’Reilly perfectly.

The writers loved incorporating real creatures into the episodes, from guinea pigs to stray dogs, because it added to Radar’s gentle nature.

But Gary didn’t just love standard domestic pets; he was deeply fascinated by all kinds of local wildlife and unorthodox creatures.

On this particular day of filming, Gary had secretly brought a rather large, non-poisonous local reptile into his dressing room.

He had rescued it near his home and decided it needed to experience the Hollywood lifestyle inside his Radar jacket pocket.

The director that day was pushing hard to finish a massive, emotionally heavy scene in the swamp involving four different main characters.

The dialogue was incredibly dense, filled with fast-paced medical jargon and heavy dramatic tension between Hawkeye and BJ Hunnicutt.

We had already rehearsed the blocking three times to make sure the cameras wouldn’t catch the studio lights in the background.

Everyone was completely exhausted, the set was hot under the heavy lights, and the director begged us for a perfect take.

Gary was supposed to enter the tent, deliver a single line of urgent tactical information, and immediately exit the frame.

He assured the director he was completely focused and ready to deliver his lines without a single mistake.

The assistant director called for quiet on the set, the cameras started rolling, and Alan began his long dramatic monologue.

Gary stood just outside the tent flap, waiting patiently for his specific verbal cue to step into the scene.

Right as Alan reached the emotional peak of his speech, Gary took his deep breath and stepped through the canvas opening.

That was the exact moment when the entire trajectory of the afternoon production schedule completely fell apart.

The reptile had managed to wiggle its way out of Gary’s internal pocket and was currently clinging directly to his collar.

As Gary opened his mouth to deliver his line, the creature extended its neck and looked directly into the camera lens.

Alan was mid-sentence, looking directly at Gary, when he froze entirely as he noticed a scaly head bobbing next to Gary’s ear.

Mike Farrell took one look at the creature, lost his train of thought completely, and bit his lower lip to keep from laughing.

Gary, completely unaware that his hidden companion had escaped, delivered his serious military line with absolute, flawless dramatic conviction.

The contrast between Gary’s intense, deadpan delivery and the strange reptile staring down the camera crew was completely absurd.

The camera operator was the first to break, as the viewfinder showed the reptile perfectly framing Gary’s face like a bizarre accessory.

A muffled snorting sound came from behind the camera rig, which immediately caused the rest of the crew to lose their composure.

The director stared at his monitor in absolute disbelief, wondering if he was experiencing heat stroke from the stage lights.

Alan finally exploded into his trademark booming laughter, pointing a finger at Gary’s neck while leaning against the cot for support.

Gary looked around the tent in total confusion, wondering why his flawless delivery was being met with absolute hysterical mockery.

He asked the crew what was so funny, and as he turned his head, the reptile shifted its weight and tickled his jawline.

Gary shrieked, jumped backward into a stack of medical crates, and accidentally knocked over a tray of surgical instruments.

The loud clattering of the metal trays made the entire situation ten times funnier to everyone watching from the sidelines.

The crew completely gave up on trying to maintain a professional workspace, with several grips literally sitting down on the floor laughing.

The director put his head in his hands, laughing so hard that no sound was coming out of his mouth anymore.

We had to stop filming for forty-five minutes just to let everyone recover their composure and to safely relocate Gary’s rescue animal.

Every single time we tried to reset the scene after that, Alan would look at Gary’s collar and immediately start giggling again.

It became a legendary running joke among the cast that Gary was trying to audition a new co-star to replace the rest of us.

The wardrobe department had to formally inspect Gary’s pockets before every single take for the rest of that production week.

Decades later on that podcast, Alan and I were laughing so hard recalling it that the audio engineer had to adjust our microphone levels.

It was those spontaneous, ridiculous moments of pure real-life comedy that kept us sane during those long, exhausting shooting schedules.

The camaraderie we shared allowed us to transition from intense wartime drama to absolute backstage absurdity in a matter of seconds.

Even now, looking at those old photos, I am reminded of how much genuine joy was mixed into the hard work of making that show.

We weren’t just actors working on a television set; we were a dysfunctional family that constantly found reasons to laugh together.

That little reptile moment never made it into the final broadcast cut, but it remains one of my absolute favorite memories of Stage 9.
