Alan Alda is leaning back in a leather chair, his eyes twinkling with that familiar, mischievous spark that hasn’t dimmed in over fifty years.

He’s recording an episode of his podcast, and the conversation has naturally drifted away from modern science and back toward the dusty, sun-scorched mountains of Malibu.

The guest has just asked him about the legendary chemistry of the MAS*H cast, wondering if the camaraderie we saw on screen was as real as it seemed.

Alan smiles, and you can practically see the memories flooding back, unbidden and vivid.

He starts talking about the arrival of David Ogden Stiers, who joined the show to play the pompous Major Charles Emerson Winchester III.

David was a brilliant addition, but he came from a world of high theater, classical music, and Juilliard-trained discipline.

For the first few weeks, he was a bit of an enigma to the rest of the rowdy, prank-loving cast.

He was precise. He was professional. He was, as Alan puts it with a chuckle, “a sitting duck for a masterpiece of a prank.”

Alan describes a particularly grueling day on the set during David’s first season.

It was one of those Southern California afternoons where the thermometer inside the canvas tents hit triple digits, and the air felt like a physical weight.

The crew was cranky, the lighting was difficult, and everyone just wanted to get the shot and go home.

The script called for a very tense, very dramatic surgery sequence in the O.R.

David had a massive, two-page monologue about the burden of being a surgeon and the intellectual superiority of his medical background.

He was in the middle of a tight close-up, the kind of shot where the slightest flicker of an eye can ruin the entire take.

Mike Farrell was standing on one side of him, and Alan was on the other, acting as his “assistants” in the surgery.

David was pouring his entire soul into the performance, his voice trembling with a controlled, Shakespearean passion that was truly impressive.

The set was deathly silent, the camera operator was locked in, and the director was holding his breath.

Alan and Mike had spent the previous ten minutes in the “scrub” area whispering like two kids in the back of a classroom.

As David reached the emotional peak of his monologue, he had to look up from the “patient” and lock eyes with Alan for a serious medical confirmation.

And that’s when it happened.

Alan pauses on the podcast, letting the suspense hang in the air for a second before he starts laughing again.

He explains that under their surgical masks, he and Mike Farrell had been hiding a secret for the last three takes.

They had taken small pieces of surgical tape and used them to pull their nostrils up into “pig snouts” and had tucked their lips under their teeth to create a look of total, slack-jawed idioty.

But that wasn’t the main event.

The real prank was what they had drawn on the inside of their masks.

As David Ogden Stiers delivered the most heart-wrenching line of his career—a line about the “sanctity of the healing arts”—Alan and Mike both reached up and “adjusted” their masks simultaneously.

They pulled the masks down just far enough to reveal that they had drawn giant, buck-toothed, drooling cartoon faces on their own skin with permanent markers.

David looked up, expecting to see the supportive, somber faces of his colleagues.

Instead, he was met with two of the most grotesque, ridiculous, and mocking expressions he had ever seen in his life.

The professional, Juilliard-trained armor didn’t just crack—it shattered.

David tried to finish the sentence. He really did.

His voice went up about three octaves as he sputtered out the word “Sacrosanct,” but it came out as more of a wheeze.

His eyes went wide, his face turned a shade of purple that matched the “blood” on the surgical table, and then he just exploded.

It wasn’t a normal laugh. It was a high-pitched, hysterical honking sound that echoed through the entire soundstage.

He doubled over, clutching the “patient” (which was actually just a bundle of rags and rubber), and he couldn’t stop.

The director, who had been watching the monitors with intense focus, was the next to go.

He saw the faces Alan and Mike were making, and he literally fell off his chair, his headset flying across the room.

Then the camera operator started to shake so hard that the frame was bouncing up and down like they were in the middle of an earthquake.

The “nurses” in the background, who were supposed to be standing in respectful silence, collapsed into heaps on the floor.

It was total, unmitigated chaos.

Alan recalls that they lost at least forty-five minutes of filming because every time David looked at them, he would start honking again.

Even when they cleaned the marker off their faces and put on fresh masks, the mere memory of the image was enough to ruin every take.

David eventually had to walk out of the tent, wander around the Malibu dirt for ten minutes, and talk to himself just to get his heart rate down.

But the most beautiful part of the story, according to Alan, was what happened afterward.

When David finally came back onto the set, he wasn’t the “serious actor from Juilliard” anymore.

He walked up to Mike and Alan, looked them dead in the eye, and whispered, “I am going to murder both of you in your sleep.”

From that day on, David was one of them.

He became one of the most prolific and creative pranksters on the set, often out-thinking Alan and Mike with his own elaborate schemes.

The “New Guy” had been broken, but in the process, he had been welcomed into a family that used humor as a shield against the darkness of the material they were filming.

Alan tells the podcast host that they were filming a show about war, and if they didn’t find those moments of absolute, unprofessional lunacy, they never would have survived the eleven years it took to tell that story.

The humor wasn’t a distraction from the work; it was the engine that made the work possible.

It made the “Major Winchester” character better, too, because once David felt safe enough to laugh, he was able to find the humanity in the pompous character he was playing.

That single afternoon of “surgical mask faces” became a piece of MAS*H legend, a story they still tell whenever the surviving cast gets together.

It reminds them that even in the most serious moments, there is room for a little bit of a “pig snout” and a permanent marker.

Looking back, it’s funny how the moments that would have gotten us fired from any other job were the ones that made us a family.

Have you ever worked with someone who was way too serious until you finally found a way to make them break?
