I was sitting there in that high-backed leather chair, the kind they only put you in when they want to archive every single breath you take for television history.

The interviewer, a nice enough fella with a very serious tie, leaned forward and looked me straight in the eye.

He asked me about the transition from the early years of MAS*H to when I joined the 4077th as Colonel Sherman T. Potter.

He wanted to know how I managed to maintain that crisp, professional, career-officer dignity while working with a pack of wild animals like Alan Alda and Mike Farrell.

I couldn’t help but chuckle because he had it all wrong.

See, the fans always saw me as the “Old Man,” the rock that kept the unit from drifting out to sea.

I was the one who had seen the Great War, the one who loved his horse and his wife, and the one who didn’t take any nonsense from the kids in the swamp.

But the truth of the matter was that I was the weakest link.

If you wanted to get a scene finished on time, you didn’t look at me.

If you wanted to keep the production on schedule, you kept Mike Farrell and Alan Alda away from my peripheral vision.

The interviewer asked me what the hardest part of filming was, and I told him it wasn’t the scripts or the heavy dramatic moments.

It was the “Stage 9” heat.

We were in those heavy surgical gowns, masks on, sweating under lights that felt like the surface of the sun.

We had been filming for fourteen hours, and we were doing a scene in the Operating Room where I had to deliver this long, stern lecture about medical supplies.

I was supposed to be furious.

I was supposed to be the moral compass.

But Mike Farrell was standing right across the table from me, and he knew something I didn’t.

He knew that I was exactly three seconds away from a total collapse.

I looked down at the “patient” on the table, and I could feel the tension in my chest beginning to vibrate.

And that’s when it happened.

Mike didn’t even say a word.

He didn’t have to.

Through that little surgical mask, all I could see were his eyes.

He did this thing—this tiny, almost imperceptible wiggle of his eyebrows—and then he made a sound.

It wasn’t a loud sound.

It was just a tiny, high-pitched “meep” that sounded like a mouse being stepped on by a very polite elephant.

That was it. That was the end of the day.

I tried to say the word “perforated,” but it came out as a strangled wheeze.

I felt my shoulders start to shake, and once the shoulders go, there is no coming back for Harry Morgan.

I dropped my head, leaning my forehead right against the prop body on the operating table, and I just started to howl.

Now, you have to understand the environment of Stage 9.

The crew was exhausted.

The director was looking at his watch, thinking about his dinner and his mortgage.

But when a man who played a stone-faced colonel for years suddenly begins to sob with laughter into a rubber torso, something happens to the collective psyche of a film crew.

The director yelled “Cut!” but it was too late.

Alan Alda, who was standing to my left, saw me go down, and he started in.

Then the nurse behind us started.

Within thirty seconds, the entire Operating Room—which was supposed to be a place of life-and-death drama—was filled with the sound of twenty people absolutely losing their minds.

I finally looked up, tears streaming down my face, my mask hanging off one ear, and I saw the head cameraman.

He wasn’t filming anymore.

He had stepped away from the eyepiece because the camera was shaking so hard from his own laughter that the shot was ruined anyway.

The director, a wonderful man who usually had the patience of a saint, walked onto the set and just stood there with his hands on his hips.

He looked at me, then he looked at Mike, who was still standing there looking completely innocent, which of course made it ten times worse.

I tried to apologize.

I really did.

I said, “I’m sorry, fellas, let’s go again. I’ve got it. I’m a professional. I was in ‘Dragnet’ for God’s sake!”

We reset.

The makeup girl came in and dabbed the sweat and the tears off my face.

The lighting guys adjusted the gels.

The room went silent.

The clapper snapped.

“Action!”

I opened my mouth to talk about the medical supplies, and I made the mistake of looking at the patient.

I remembered the “meep.”

I didn’t even get the first syllable out before I was doubled over again.

This went on for six takes.

Six.

By the fourth take, the director wasn’t even mad anymore.

He was sitting in his chair with his head in his hands, laughing so hard he couldn’t even call for the next take.

He just waved a limp hand in the air.

Every time I looked at Mike Farrell, he had this look of grave concern on his face, which was the deadliest thing he could have done.

He’d say, “Harry, are you okay? Do you need some water, Harry?” in that smooth, helpful voice of his.

And I’d just point a finger at him and gasp, “You… you devil.”

We eventually had to take a twenty-minute “cool down” break where I was literally forbidden from speaking to or looking at any other cast members.

They sent me to my trailer like a naughty schoolboy.

I sat there in the dark, trying to think about something sad.

I thought about taxes.

I thought about traffic on the 101.

I thought about the heat.

But then I’d hear a muffled burst of laughter from the soundstage next door and I’d start all over again.

That was the magic of that show.

People ask me all the time if it was a “happy set.”

Happy doesn’t even cover it.

We were a family that had stayed up too late and worked too hard, and we found the absolute absurdity in the middle of the tragedy we were portraying.

When I finally got the line out on the seventh take, the entire crew broke into spontaneous applause.

Not because the acting was particularly brilliant—it wasn’t—but because we had finally survived the “meep.”

I remember walking off the set that night with my arm around Mike’s shoulder.

I told him if he ever did that again, I’d have him transferred to a weather station in the Arctic.

He just smiled and said, “Colonel, I don’t know what you’re talking about.”

Looking back on it now, those are the moments I miss the most.

Not the awards or the big speeches.

Just the feeling of being sixty years old and laughing so hard you can’t stand up, surrounded by people who feel exactly the same way.

It reminds you that even in the toughest “ORs” of life, if you can find one person to make a funny noise at you, you’re going to be just fine.

Do you have a friend who can make you lose your composure with just a single look?
