You know, people ask me all the time about the dresses.

They want to know if the heels hurt or which chiffon number was my favorite.

But when I sit down for these retrospective podcasts, like the ones where we really get into the weeds of what it was like on Stage 9, my mind doesn’t go to the wardrobe department.

It goes to the Operating Room.

The OR was the heart of the show, but God, it was a miserable place to film.

I remember sitting in a studio recently, the headphones hugging my ears, and the host asked me a question I hadn’t really heard framed that way before.

He asked, “Who was the one person who could break the tension when the 4077th felt like it was actually under fire?”

I didn’t even have to think about it.

The answer was always Harry Morgan.

Now, you have to understand the environment of those OR scenes.

We called them the “killing fields” of our patience.

The lights were positioned so low to simulate the surgical lamps that the temperature on the floor would regularly hit a hundred degrees.

We were wearing heavy canvas gowns over our clothes, rubber gloves that made your hands sweat until they pruned, and those masks.

The masks were the worst because you couldn’t see anyone’s mouth.

You had to act entirely with your eyes, and if you were tired, it showed.

By the time Harry joined us in the fourth season, we were a well-oiled machine, but we were a tired one.

We had been doing these grueling sessions for years.

Harry came in as Colonel Potter, this legendary veteran actor who we all respected, but we didn’t know yet that he was the most mischievous man in Hollywood.

There was one afternoon where we were filming a particularly heavy episode.

The script was dense, full of that rapid-fire medical jargon that Alan Alda loved to write.

We had been at it for seven hours straight.

The director wanted this one long, continuous tracking shot.

The camera would start on me, move past Mike Farrell, circle around Alan, and end on a close-up of Harry delivering a poignant line about the waste of young lives.

It was the kind of shot that took forty-five minutes to light and an hour to rehearse.

If one person tripped over a line or a prop malfunctioned, the whole three-minute take was junk.

We were on take twelve.

The tension in the room was thick enough to cut with a scalpel.

The director, Burt Metcalfe, was rubbed raw.

He called for quiet on the set, and you could hear a pin drop on the plywood floor.

The camera started its slow, rhythmic crawl.

I did my bit, Alan was perfect, and Mike was sweating through his gown just right.

The camera swung around to Harry.

He looked like a statue of dignity, the perfect career soldier.

He leaned over the “patient,” his hands deep in the fake chest cavity.

He looked up, right into the lens, prepared to deliver the emotional climax of the episode.

And that’s when it happened.

From somewhere deep inside Harry’s surgical glove came a sound that didn’t belong in a mobile army surgical hospital.

It was a sharp, high-pitched, rhythmic squeak.

Harry didn’t say his line.

Instead, he moved his hand inside the patient’s “body,” and every time he squeezed his fingers, the squeaker went off.

Squeak. Squeak. Squeak-squeak.

He was looking directly at Alan Alda with the most somber, professional expression you’ve ever seen on a human being.

He looked like he was announcing the end of the world, but his hand was playing a solo on a dog toy.

The silence that followed was the loudest thing I’ve ever heard in my life.

Alan was the first to go.

He tried to swallow the laugh, which resulted in this strange, strangled honking sound behind his mask.

That was the signal for the rest of us.

Mike Farrell’s shoulders started heaving.

I was standing behind them, and I just doubled over, clutching my stomach.

But Harry?

Harry stayed in it.

He kept “operating” with that toy, his eyes never wavering from the script’s emotional intent.

He looked at the director and said, in that perfect Colonel Potter rasp, “I think I found the problem, Doctor. This man has swallowed a mallard.”

That was the end of the day.

There was no coming back from that.

The crew, who usually stayed stoic behind the cameras, were losing their minds.

Dominick Palmieri, our cinematographer, actually had to step away from the camera because he was laughing so hard he was vibrating the entire rig.

He told us later that he saw the whole thing through the viewfinder and just watched his career flash before his eyes because he knew the take was ruined, but he couldn’t stop.

Burt Metcalfe, the director, was sitting in his chair with his head in his hands.

For a second, we thought he was angry.

The room went a little quiet as we waited for the explosion.

Then we saw his back shaking.

He looked up, and his face was bright red, tears streaming down his cheeks.

“Harry,” he gasped, “we’ve spent sixty thousand dollars on this shot today.”

Harry just pulled the little rubber squeaker out of his glove, held it up like a piece of shrapnel he’d just extracted, and shrugged.

“I thought the scene lacked a little subtext, Burt,” he said.

“I wanted to give the audience something to really think about.”

It took us twenty minutes to reset, and even then, we couldn’t look at Harry.

Every time we tried to start the scene, Alan would catch a glimpse of Harry’s hand and start giggling like a schoolboy.

We eventually had to film Harry’s close-up separately because the rest of us were a lost cause.

But the amazing thing was what it did for the energy on set.

Before that prank, we were exhausted and irritable.

After it, we were a family again.

We finished the rest of the episode in record time because we were all riding that high of collective joy.

That was Harry’s gift.

He knew exactly when the pressure was too much, and he knew that the only way to break it was to be absolutely, professionally ridiculous.

He was the dean of the school of “don’t take yourself too seriously,” and we were all his willing students.

Years later, I asked him where he even got a squeaker that small.

He just winked at me and said he kept a stash of them in his trailer, right next to his cigars.

He’d been planning it for three days, waiting for the moment when we were at our absolute lowest point of the week.

He was a tactical genius of comedy.

When I look back at those eleven years, I don’t remember the long hours or the heat as much as I remember the sound of that toy in the middle of a war zone.

It reminds me that even in the most serious work, there is always room for a little bit of nonsense.

It’s what kept us sane, and it’s what made the show what it was.

We weren’t just actors playing doctors; we were friends who genuinely loved making each other laugh.

And nobody did it better than the Colonel.

I think about that every time I’m having a rough day at work.

I just imagine a squeaker in my glove and it all feels a little lighter.

What’s the one moment in your own life where a well-timed joke saved a stressful situation?
