I was sitting in this small, dimly lit recording studio for a podcast a few months ago, and the host asked me something I didn’t expect. Usually, people want to know about the bears or the phone calls to Sparky, but he asked about the physical comedy that didn’t make it onto the screen. It was such a specific question that it immediately took me back to the Fox Ranch in Malibu.

I could almost smell the dust and the diesel fumes of the compound. We were filming an episode in the middle of a typical California heatwave, and everyone was a little bit on edge. The crew was tired, the actors were sweating through their fatigues, and we were all trying to maintain that high-energy, fast-paced rhythm that the show was known for.

In this particular scene, I was playing Radar, as usual, and I had to deliver a stack of papers to Colonel Potter. Harry Morgan was a pro, as you know, but he had this way of looking at you over his glasses that could make you forget your own name if you weren’t careful. The scene was supposed to be a standard bit of exposition—Radar enters, drops off the casualty reports, makes a quick quip, and exits.

We had rehearsed it twice without any issues. The dialogue was sharp, and the timing felt right. But on a set like ours, the smallest variable can change everything. In this case, it was a brand-new prop. The property master had brought in a fresh set of clipboards that were supposedly more period-accurate, but they were incredibly slick, almost greasy from whatever finish they had used.

I remember standing outside the office door, waiting for my cue. I could hear Harry and Alan inside, wrapping up their part of the dialogue. I adjusted my hat, took a deep breath, and gripped the stack of clipboards to my chest. They felt unusually heavy and very, very slippery.

The director called for action. I felt that familiar rush of adrenaline as I stepped over the threshold into the office. I had a specific line about a delivery from headquarters that required a bit of a flourish as I handed the papers over. Everything was moving in high gear.

As I approached the desk, I noticed Harry was leaning forward, really leaning into his character’s stern authority. The camera was tight on us. I reached out to extend the top clipboard, intending to slide it perfectly onto the blotter right in front of him.

But the friction wasn’t there. Instead of a smooth handoff, I felt the entire stack start to vibrate against my jacket. My fingers began to lose their purchase on the wood and metal. I tried to tighten my grip, but that only made the bottom boards shift even further out of alignment.

The silence in the room was palpable as everyone watched my hands. I knew I had to finish the motion, but the physics of the situation were rapidly deteriorating. I looked Harry right in the eye, trying to stay in character, even as I felt the weight of the props beginning to give way.

And that’s when it happened.

The top clipboard didn’t just slide onto the desk; it took flight. Because of the slick finish, it shot out of my hand like a greased pig, sailed right over the desk, and landed squarely in Harry Morgan’s lap. But it didn’t stop there. The momentum caused the rest of the stack to follow suit, creating a literal waterfall of wooden boards and fluttering papers that buried the Colonel’s desk in a matter of seconds.

One clipboard actually bounced off the edge of the desk and struck the bell on the side of the table, letting out a loud, resonant “ding” that sounded like the end of a boxing round.

For a second, the room was deathly quiet. I was standing there with my arms still extended, empty-handed, looking like a magician whose trick had gone horribly wrong. Harry just sat there, buried up to his chest in paperwork, staring down at his lap with an expression of pure, unadulterated confusion.

Then, Harry slowly looked up at me. He didn’t break character at first. He just peered over those spectacles, took a long beat, and said, in that perfect Colonel Potter rasp, “Radar, did headquarters send these, or did they launch them from a catapult?”

That was the end of the take. Alan Alda, who was standing off to the side, let out a bark of laughter that echoed through the entire soundstage. Once Alan started, it was over for the rest of us. The director tried to hold it in, but he ended up doubling over his chair, clutching his stomach.

The humor escalated because I tried to be helpful. I lunged forward to start picking up the mess, but in my haste, I tripped over the corner of the rug and landed face-first onto the desk, right on top of the casualty reports. Now, instead of just a mess of papers, we had a Radar-shaped pile of chaos in the middle of the shot.

The crew was absolutely losing it. The camera operators were literally shaking, and you could see the frame bouncing up and down because they couldn’t stay still. We had to stop filming for at least twenty minutes because every time Harry and I looked at each other, we’d start up again.

What made it legendary was that Harry wouldn’t let it go. For the rest of the day, every time I walked into a room, he would duck behind his desk or put his hands over his head as if he were expecting an air raid. He started calling it the “Great Clipboard Barrage of ’74.”

Even the grips and the lighting guys were in on it. Later that afternoon, when I went to my chair, someone had taped a small piece of paper to it that said “Target Zone.” It became one of those inside jokes that just weaves itself into the fabric of the production.

That’s the thing about MAS*H. We were dealing with such heavy subject matter most of the time—life and death, surgery, the tragedy of war—that when something truly absurd happened, the release was enormous. We needed those moments. We needed to laugh until our sides ached just to balance out the emotional weight of the stories we were telling.

Looking back, that prop malfunction wasn’t just a blooper. It was a moment of pure, human connection. It reminded us that no matter how serious the scene was, we were still just a bunch of people in a tent in the middle of a ranch, trying to make something special.

Harry and I talked about that moment years later at a reunion. He told me it was one of the few times he genuinely couldn’t keep a straight face on set. He said he could still hear that “ding” of the bell every time he saw a clipboard.

It’s those little accidents that make the best memories. You can script a joke and rehearse it until it’s perfect, but you can’t script the sight of a veteran actor being buried under a mountain of casualty reports because of a slippery piece of wood.

I think about that day often when I see a rerun of the show. I see the office, I see the desk, and I can still feel the slickness of those clipboards in my hands. It brings a smile to my face every single time.

Those days were long, and the work was hard, but the laughter was real. It was the glue that held us all together.

Do you have a favorite “Radar” moment that always makes you smile when you watch the show?
