You know, people always ask me about the transition from a show like Dragnet to a show like MAS*H.

They are two completely different universes, really.

In Dragnet, Jack Webb wanted everything done by the book, on time, and with a very specific, clipped cadence.

There wasn’t much room for horsing around when you were playing Officer Bill Gannon.

So, when I stepped onto the set of the 4077th to play Sherman Potter, I brought that same old-school, professional discipline with me.

I figured I was the “old man” of the group, and I needed to set a certain standard of decorum for these younger, wilder actors.

I remember sitting in a chair during a late-career retrospective interview a few years back, and they showed a still of Potter’s office.

Just seeing that desk again brought a flood of memories back, but one specific morning stands out clearer than the rest.

We were about midway through my first few seasons, and the cast had finally realized that behind my gruff exterior, I was actually a bit of a softie who loved a good laugh.

But they hadn’t quite “broken” me yet.

I still took the work very seriously, especially the scenes where Potter was alone in his office, writing home to his wife, Mildred.

Those were the anchors of the character for me.

On that particular morning, we were scheduled to film a very quiet, sentimental scene.

Potter was supposed to be sitting at his desk, looking at the photographs of his family, and reflecting on how much he missed home.

The lighting was dim, the set was uncharacteristically quiet, and I was really trying to get into that somber, lonely headspace.

I walked onto the set, nodded to the crew, and took my seat behind the heavy wooden desk.

I didn’t look down at the props yet; I wanted to save that emotional connection for when the cameras were actually rolling.

The director called for silence, the assistant director cleared the frame, and the room went completely still.

I could feel the weight of the scene building in my chest as I prepared to deliver a heartfelt monologue to a cold room.

I took a deep breath, centered myself, and waited for the cue.

And that’s when it happened.

The red light on the camera went on, and I began the scene by slowly reaching out to touch the framed photo of my beloved wife, Mildred.

In the script, I was supposed to look at her face and find the inspiration to keep going despite the horrors of the war surrounding us.

I tilted the frame toward me, prepared to see the lovely, silver-haired woman who usually occupied that spot.

Instead, I found myself staring directly into the eyes of Mike Farrell.

He wasn’t just in the photo; he was in full costume as a 1940s housewife.

He was wearing a floral housecoat, a string of fake pearls, and a wig that looked like it had been stolen from a grandmother’s closet.

He had this demure, slightly seductive expression on his face that was so absurd it nearly short-circuited my brain.

My first instinct was to keep going—I was a professional, after all.

I tried to pivot my gaze to the next photo, the one of Potter’s daughter and son-in-law.

I shifted my eyes to the smaller frame on the right, hoping for some sanity.

There, looking back at me with a giant pink bow pinned to his hair and a look of mock-innocence, was Alan Alda.

He was wearing a ruffled dress that looked two sizes too small, and he was clutching a stuffed bear.

Behind him, posing as the “husband,” was Jamie Farr, sporting his usual Klinger-style mustache but wearing a very serious tuxedo and holding a pipe.

I felt the first twitch in my cheek.

It was that specific “Morgan tremor” that the cast always watched for.

I tried to swallow the laugh, but then I made the fatal mistake of looking at the third photo on the edge of the desk.

It was supposed to be my grandson.

Instead, it was a close-up shot of David Ogden Stiers, looking incredibly pompous but wearing a baby bonnet and sucking his thumb.

The silence on the set was suddenly broken by a sound that came from the back of the room.

It wasn’t me. It was the camera operator.

I looked up and saw the entire camera rig shaking because the poor man was trying so hard to suppress his laughter that his whole body was vibrating.

Then I looked over at the director, who had his face buried in his hands, his shoulders heaving up and down.

I looked back down at “Mildred” Mike Farrell, and that was the end of it.

I let out this high-pitched, wheezing cackle that we eventually started calling the “Morgan Giggles.”

Once I started, there was no stopping.

I was bent over the desk, laughing so hard that tears were streaming down my face and hitting the glass of the prank photos.

The entire crew erupted.

It turns out the cast had spent a good portion of the previous afternoon in the wardrobe and makeup trailers, secretly staging a full family photo shoot just to get this one reaction out of me.

They had even bribed the prop master to swap the photos out seconds before I walked onto the set so I wouldn’t see them during the rehearsal.

We must have lost twenty minutes of filming time because every time we tried to reset, I would look at Mike Farrell in that wig and lose it all over again.

Alan kept saying, “What’s the matter, Dad? Don’t you recognize your own flesh and blood?”

Jamie Farr started humming a lullaby, and David Ogden Stiers just stood in the corner of the set, perfectly maintaining his “baby” expression from the photo.

That moment became legendary on the set because it was the day I stopped being the “guest from Dragnet” and truly became a member of the family.

They realized that if they could break the Colonel, they could do anything.

For the rest of the series, I never knew what I was going to find when I opened a drawer or looked at a prop.

But it taught me something important about that show.

We were dealing with such heavy subject matter every day—death, surgery, the exhaustion of war—that if we didn’t have those moments of absolute, ridiculous anarchy, we probably would have lost our minds.

Those photos stayed on that desk for a long time afterward, hidden behind the real ones, just as a reminder that we were all in it together.

It’s funny how a piece of paper and a bad wig can turn a group of coworkers into a lifelong brotherhood.

Whenever I think of MAS*H, I don’t think of the awards or the ratings first.

I think of Mike Farrell’s face in that floral dress, and I start to giggle all over again.

It’s those little moments of shared joy that make the hard work worth it, don’t you think?

If you could pull a harmless prank on your boss or a coworker today, what would it be?
