I was recording an episode of my podcast not too long ago, and my guest completely turned the tables on me.

They asked a question that caught me entirely off guard.

They said, “Alan, you guys shot over two hundred episodes of MAS*H. You were constantly surrounded by comedy. But when was the hardest you ever laughed on set? Like, physically unable to do your job?”

I didn’t even have to think about it.

The memory snapped right back into my brain, like it happened yesterday instead of fifty years ago.

I took a breath and transported myself back to Stage 9 at the Twentieth Century Fox lot.

It was season three.

We were filming an episode called “The General Flipped at Dawn.”

If you know the show, you know this was the episode where Harry Morgan made his very first appearance.

He wasn’t playing our beloved Colonel Potter yet.

He was playing Major General Bartford Hamilton Steele, a military brass who was completely, wonderfully out of his mind.

Harry was already a Hollywood legend at that point.

Wayne Rogers and I had immense respect for him and we wanted to be on our absolute best behavior.

We were setting up for the big court-martial scene.

It was a master shot, meaning the camera was wide, capturing the whole room at once.

Wayne and I were seated at the defense table, trying to look incredibly solemn and serious.

Harry was sitting at the judge’s table, presiding over the madness.

The soundstage was sweltering hot.

The canvas of the set trapped the heat from the heavy studio lights.

Everyone was sweating, tired, and just wanting to get the master shot in the can.

Gene Reynolds, our director, called for action.

The room fell completely silent.

Harry began his monologue.

He was delivering a stern speech, but he decided to put this bizarre, staccato rhythm into his delivery.

Wayne and I were staring straight ahead.

I could feel the air in the room start to shift.

The tension was unbearable.

Something felt incredibly dangerous.

And that’s when it happened.

Harry was in the middle of a sentence, and suddenly, he did this tiny, almost imperceptible thing with his eyes.

They bulged out of his head for a fraction of a second, and his voice went up half an octave on a single word.

It wasn’t in the script.

It was pure, unadulterated comedic instinct from a master of the craft.

I was sitting right next to Wayne.

Now, Wayne Rogers was a wonderful actor, but he was a notoriously terrible giggler.

If Wayne went, I went. It was an unavoidable chain reaction.

I felt Wayne’s shoulder brush against mine, and it was vibrating.

He was physically shaking.

I squeezed my eyes shut and bit the inside of my cheek so hard I actually tasted copper.

I was furiously telling myself, “Alan, do not ruin this take. This is Harry Morgan. Be a professional.”

But the vibration from Wayne’s shoulder traveled directly into my own body.

A weird, strangled noise squeaked out of my nose.

Gene Reynolds yelled, “Cut!”

We profusely apologized, wiped our watering eyes, and reset our positions.

Take two.

Action.

Harry starts again.

He gets to the exact same word, and he leans into it even harder.

The eye bulge is slightly bigger.

The pitch of his voice is undeniably higher.

Wayne absolutely loses it.

He bends over the wooden table, burying his face in his arms, his shoulders violently heaving.

I completely broke character.

I threw my head back and just roared with laughter.

Gene yells cut again.

Take three.

By now, the contagion had completely spread across the room.

Larry Linville, who played Frank Burns, was sitting right behind us.

Larry was a master of maintaining a rigid, tight-lipped military posture.

But I looked back at him, and his face was the color of a ripe eggplant.

He was holding his breath to keep from laughing, looking like he was about to pass out.

Meanwhile, Harry is just sitting there at the judge’s bench.

He hasn’t cracked a single smile.

He is looking at us with this deadpan, disappointed expression, making the situation a thousand times funnier.

Take four.

We barely make it three words into the scene before Wayne snorts.

It was this loud, ridiculous sound that echoed off the studio walls.

He desperately disguised it as a cough, but nobody bought it.

Take five.

The crew is completely gone.

The boom operator put his microphone down on the floor because his arms are shaking too much to hold the pole steady.

I can hear the camera operator behind the lens trying to muffle his own chuckles.

The entire soundstage has descended into absolute chaos.

The makeup department kept rushing in to dab our faces because we were sweating and crying at the same time.

My ribs were physically aching.

My jaw was completely cramped.

I was begging Harry with my eyes, “Please, just do it normally so we can go home.”

But Harry was a mischievous genius.

He knew exactly what he was doing to us, and he was secretly reveling in it.

I think we ruined seven or eight takes of that one wide shot.

Gene Reynolds finally had to pull us aside like misbehaving children.

He literally instructed Wayne and me to stare at our boots and not make eye contact with Harry.

Even then, just hearing the bizarre rhythm of Harry’s voice was almost enough to send us over the edge.

When we finally managed to get a print, a collective sigh of relief washed over Stage 9.

We collapsed into our canvas cast chairs, completely drained.

Harry calmly walked over to us.

The deadpan mask slipped away, and he gave us this wonderful, warm, grandfatherly grin.

He just patted me gently on the shoulder, winked, and walked away.

Looking back, that day was a major turning point for the show.

When McLean Stevenson left the series a year later, the producers needed someone to command the 4077th.

There was zero hesitation.

We all knew we needed the man who brought our production to a grinding halt with a simple twitch of his eye.

We spent eleven years simulating a war zone in the backlots of Los Angeles.

We worked incredibly long hours, often feeling overwhelmed and emotionally spent.

But when you get a group of people who can make each other laugh until they cannot stand up, it becomes a family.

That scene with Harry remains one of my absolute fondest memories.

Laughter has this incredible healing power, especially when it catches you completely by surprise.

Have you ever been in a situation where you couldn’t stop laughing, even though you knew you were supposed to be completely serious?
