I was sitting on a plastic chair at one of those big fan conventions in California.

The room was packed with people wearing olive drab t-shirts and hats with fishing lures on them.

A young man stood up at the microphone in the center aisle and asked me something I’ve been asked a thousand times.

He wanted to know who the funniest person on the set of MAS*H really was.

People always expect me to say Alan Alda because he’s so quick, or maybe Jamie Farr because of the outfits.

But I leaned into the microphone and told him that the real danger to our productivity was actually Harry Morgan.

Harry was the most professional, seasoned actor you could ever hope to meet.

He came from that old school of Hollywood where you knew your lines, you hit your marks, and you didn’t waste the studio’s money.

But once Harry got the giggles, it was like watching a dam break.

There was one particular morning at the Fox Ranch in Malibu where the heat was already hitting ninety degrees by eight a.m.

We were filming a scene in the mess hall, which was always a nightmare because of the flies and the smell of the prop food.

The script called for a very serious briefing.

Colonel Potter had to deliver this long, winding monologue about a new army regulation regarding the disposal of kitchen waste.

It was filled with military jargon and technical terms that were designed to be boring.

Harry had been practicing it in his trailer all morning, and he was ready.

We were all gathered around the table, trying to look appropriately disciplined and exhausted.

I remember looking over at Alan, and I could tell he was struggling just to stay awake in the heat.

Harry stood at the head of the table, cleared his throat, and looked us all in the eye with that classic Potter sternness.

The camera was rolling, the sound was clear, and the director was holding his breath for a perfect one-take delivery.

And that’s when it happened.

Harry reached the middle of this very dense sentence about “sanitary refuse containers” and his tongue just decided to go on vacation.

Instead of saying “refuse containers,” he said “confuse retainers,” and then he tried to correct himself.

But instead of stopping, he kept going, and the words coming out of his mouth weren’t even English anymore.

It sounded like a mix of Swedish and some kind of alien dialect.

He stopped, looked at the script supervisor, and said with a completely straight face, “Did I say that, or did I just have a stroke?”

That was the end of it.

Alan Alda was the first to go.

He didn’t just laugh; he did that thing where he fell backward off his bench and ended up on the floor.

Then Mike Farrell started, and Mike has this deep, booming laugh that vibrates through the floorboards.

I tried to keep my “Radar” face on because I was supposed to be the disciplined one, but my shoulders started shaking so hard I had to hide behind my clipboard.

Harry just stood there, looking at us like we were all insane, which only made it worse.

The director, Burt Metcalfe, called “Cut,” but nobody could stop.

We tried to reset the scene, but every time Harry opened his mouth to say the word “sanitary,” he would catch Alan’s eye and start chirping like a bird.

I’m not kidding, he actually started making bird noises because he knew it would destroy us.

The crew was trying to be professional, but the camera operator was literally shaking the camera because he was laughing so hard into his eyepiece.

We spent the next forty-five minutes trying to get through that one paragraph.

We would get three words in, and then someone would sniffle or make a tiny sound, and the whole room would explode again.

It became a competitive thing where Harry would try to say the line as fast as humanly possible just to get it over with.

But the faster he went, the more he sounded like a chipmunk on caffeine.

At one point, the producer actually had to come down to the set because he wondered why we hadn’t moved on to the next scene yet.

He found the entire cast of the number one show on television sitting in the dirt outside the mess hall, trying to breathe.

Harry was sitting on a crate, wiping tears from his eyes with a handkerchief, saying, “I’m a professional, I’ve worked with Jack Webb, I shouldn’t be doing this.”

But then he looked at me and said, “Radar, go find me a confuse retainer,” and we were gone for another ten minutes.

That was the magic of that set.

We were working twelve, fourteen hours a day in the sun, wearing heavy wool clothes, and dealing with some very heavy subject matter in the scripts.

If we didn’t have those moments where we completely lost our minds over a mispronounced word, I don’t think the show would have lasted eleven years.

It wasn’t just a blooper; it was a release valve.

Whenever I watch that episode now, I can see the slight redness in our eyes and the way Alan is biting his lip during the briefing.

The audience sees a serious Colonel Potter giving orders to his staff.

But I see a group of friends who were one syllable away from a total nervous breakdown.

Harry Morgan was the anchor of that show, but he was also the one who taught us that if you can’t laugh at yourself when you’re failing, you’re in the wrong business.

We finally got the take on the nineteenth try, but only because the director threatened to make us eat the prop food if we missed it again.

That threat worked instantly.

Nothing motivates an actor like the fear of eating three-day-old stage Salisbury steak.

I still think about that day every time I stumble over a word in my daily life.

I just stop, look around, and wait for someone to fall off a bench.

It makes the world feel a little bit more like the 4077th.

There is something beautiful about a group of people who love each other enough to make work impossible for an hour.

Do you have a favorite memory of a time when you couldn’t stop laughing in a place where you were supposed to be serious?
