I remember sitting in a recording booth for a podcast a few years ago, and the host asked me a question I’ve heard a thousand times: “David, how did you keep such a straight face while playing Charles Emerson Winchester III?”

The truth is, I didn’t.

People think of Charles as this pillar of aristocratic dignity, this man who was perpetually offended by the very concept of the 4077th.

And I took that role seriously.

I felt that for the comedy to work, Charles had to be the anvil that the others struck.

If I cracked, the character vanished.

But there was one man on that set who made my professional discipline feel like a house of cards in a hurricane.

That man was Harry Morgan.

We were filming a scene in the Swamp late one Tuesday night.

The air was thick with the smell of old canvas and that stale, dusty scent that comes from being under studio lights for fourteen hours straight.

Everyone was exhausted.

When actors get that tired, we enter a state of “giggle-vulnerability.”

You reach a point where the most mundane thing becomes the funniest event in human history.

In this particular scene, I had a long, winded monologue where I was supposed to be lecturing Hawkeye and B.J. about the finer points of some obscure medical procedure.

Harry, as Colonel Potter, had to walk in, deliver a single line of authority, and then stand there while I continued my pompous rant.

I remember looking at the script and thinking, “Just get through this, David. One more take and we can all go to sleep.”

I began the speech, my voice filled with that signature Winchester arrogance.

I was doing quite well, hitting every syllable with the precision of a metronome.

I saw Alan and Mike across from me, their eyes glazed over with legitimate exhaustion, which actually helped the scene.

Then, the door to the Swamp swung open, and in walked Harry.

He looked me dead in the eye, his face a mask of stern, military discipline.

He didn’t say a word at first.

He just stood there, waiting for his cue.

But I noticed something.

Harry’s eyes were twinkling with a very specific, very dangerous kind of mischief.

And that’s when it happened.

I saw his jaw move.

It wasn’t a line.

It wasn’t even a twitch.

Harry Morgan, a veteran of the screen who could command a room with a single glance, simply shifted his dentures.

He did it in a way that only I could see from my angle, a subtle, rhythmic clicking that made his mouth look like it was working through a piece of invisible, very tough saltwater taffy.

It was such a tiny, ridiculous gesture, but in the silence of that exhausted set, it felt like a grenade going off.

I stopped mid-sentence.

My mouth was open, the word “surgical” hanging in the air, but no sound came out.

I felt a bubble of laughter rise from my stomach, and I fought it with everything I had.

I bit the inside of my cheek so hard I’m surprised I didn’t draw blood.

I looked up at the ceiling, trying to find a spot of light to focus on, anything to reclaim my dignity.

I tried to restart the line.

“The… the surgical implications…”

I looked back down at Harry.

He hadn’t moved a muscle, except for those dentures.

Click. Click. Click.

His face was still perfectly stern, perfectly “Colonel Potter,” which only made the absurdity of the situation ten times worse.

I completely lost it.

I didn’t just chuckle.

I doubled over, my forehead hitting the edge of the table, and I roared with a laughter that I can only describe as hysterical.

The entire room went silent for a heartbeat because, as I said, David Ogden Stiers did not break.

And then, like a row of dominoes, everyone else went.

Alan Alda started howling.

Mike Farrell was leaning against the bunk, shaking.

The crew, who had been ready to go home, were suddenly dropping their booms and leaning against the cameras, gasping for air.

But the worst part—the part that made it legendary—was Harry’s reaction.

He didn’t laugh.

He stayed in character.

He looked around at the chaos with this expression of deep, fatherly concern.

He walked over to me, placed a hand on my shoulder, and said in that gravelly Potter voice, “Son, are you having a seizure? Should we get the orderlies?”

That was the end.

I was on the floor.

I was literally on the floor of the Swamp, clutching my stomach, tears streaming down my face.

Every time I tried to stand up, Harry would give me another “stern” look, perhaps a slight raise of one eyebrow, and I would collapse all over again.

The director, who I believe was Hy Averback that night, eventually gave up.

He sat down in his chair and just watched us.

We tried to film that take nineteen more times.

Nineteen.

Every single time I got to the word “surgical,” I would think of Harry’s teeth, and the dam would break.

The crew started placing bets on how many words I could get out before the laughter started.

It became this beautiful, shared moment of insanity that happens when a group of people has worked together for years.

There was no ego in it.

There was just this overwhelming sense of joy.

I eventually had to ask Harry to leave the set so I could finish my monologue to a piece of tape on the wall.

He walked out, puffing on his cigar, looking back one last time with that wicked glint in his eye.

Years later, when we would have reunions, Harry would just look at me across a dinner table and click his teeth once.

I would start laughing all over again.

It reminded me that no matter how serious the work was, or how grim the subject matter of the show could be, we were essentially just a bunch of friends playing in the mud.

That laughter was the fuel that kept us going through eleven seasons.

It was the bridge between the characters we played and the people we actually were.

Charles Winchester would have been appalled by such a display of emotion.

But David Ogden Stiers needed it.

We all did.

It’s those moments of pure, unadulterated silliness that I miss the most when I think back on those years.

The show gave us a legacy, but the laughter gave us a family.

Do you have a favorite memory of a time you couldn’t stop laughing at the absolute worst possible moment?
