I was sitting in a soundproof studio recently, doing an interview for a popular comedy podcast.

The host, a very sharp guy who knows everything about seventies television, was asking me about the magic of Hollywood illusion.

He leaned into the microphone and asked me what the single most physically miserable day on the set of MAS*H actually was.

I didn’t even have to think about it.

I just immediately started laughing.

When people watch the show at home, they see us shivering in the bitter, freezing cold of a Korean winter.

They see the snow falling, the heavy breath, the thick wool coats, and our desperate attempts to stay warm around a tiny, smoky camp stove.

What they don’t see is the hilarious reality of filming television in Southern California.

We shot our exterior scenes at the Fox Ranch in the rugged mountains of Malibu.

On this particular day, it was late August.

The temperature was hovering somewhere around a hundred and four degrees.

There was absolutely no breeze in the canyon.

The script, however, called for a massive, brutal winter blizzard.

The wardrobe department brought out full arctic gear.

We were forced to wear heavy thermal long johns, thick wool sweaters, massive military parkas, heavy boots, scarves, and gloves.

We were standing in the middle of a dirt lot, baking in the California sun, dressed for the tundra.

The heat was completely suffocating.

You could feel the sweat pooling in your heavy boots before the director even called for action.

To make matters worse, the special effects crew brought in massive industrial fans to blow fake snow all over the camp.

We were all standing outside the Swamp, trying our best not to pass out from heatstroke, waiting for the cameras to roll.

The tension on set was incredibly high because we were all so physically exhausted and uncomfortable.

Everyone just wanted to get the scene over with and take the coats off.

We finally took our marks.

The giant industrial fans roared to life.

The fake snow started blasting us directly in the face.

And that’s when the disaster happened.

What the audience at home didn’t know was what that fake snow was actually made of.

The special effects department had decided to use instant potato flakes.

In theory, it was a brilliant Hollywood trick.

The flakes were light, they fluttered perfectly in the wind, and they looked exactly like real snowflakes on camera.

But the effects guys hadn’t accounted for the basic biology of five actors wearing heavy wool in a hundred-and-four-degree heatwave.

We were sweating profusely.

Our faces were completely drenched.

So when those massive fans blasted the instant potato flakes into our faces, the fake snow didn’t just bounce off.

It stuck.

The potato flakes hit our dripping wet faces, our sweaty necks, and our damp wool sweaters, and immediately began to rehydrate.

Within seconds, our bitter Korean blizzard had turned into a full-blown culinary disaster.

I was trying to deliver a very serious, dramatic line about the dangers of frostbite.

I looked over at Wayne Rogers, who was supposed to be shivering next to me in the freezing cold.

His face was completely covered in thick, sticky mashed potatoes.

Little clumps of it were forming on his eyebrows and sliding slowly down his nose.

He looked like he had just lost a fight at a terrible all-you-can-eat buffet.

I tried to keep a straight face.

I really did.

I bit the inside of my cheek, stared at his boots, and tried desperately to focus on the script.

But then Wayne shifted his weight, wiped his brow with his heavy wool glove, and smeared a giant streak of mashed potatoes directly across his forehead.

He looked at me with this completely deadpan, exhausted expression.

Underneath his breath, he whispered, “Needs salt.”

That was it.

I completely broke.

I let out a laugh so loud it startled the sound mixer.

Once I started laughing, Wayne started laughing too.

His shoulders were shaking, which caused more potato flakes to land on his sweaty neck and instantly turn to mush.

Gary Burghoff walked out of the tent to deliver his line, took one look at our starchy faces, and doubled over in hysterics.

The director yelled cut from the shade of his umbrella.

He was annoyed at first, but then he walked over to us to see what was ruining the emotional take.

When he saw his serious cast standing in the blazing Malibu sun, wearing arctic parkas and covered in actual side dishes, he lost it too.

The entire crew started roaring.

The camera operator had to step away from the lens because he was laughing so hard he was shaking the heavy equipment.

The makeup department came running in with towels and water bottles, frantically trying to clean us up.

But every time they wiped the potatoes off, the fans would blow more flakes, and the cycle would start all over again.

We were laughing so hard we couldn’t breathe, which only made us sweat even more.

The harder we laughed, the more potatoes we cooked on our own faces.

It was pure, chaotic absurdity.

We had to stop filming for almost an hour just to calm everyone down and scrape the lunch menu off our wardrobe.

We finally managed to get the shot by staring directly at the dirt and holding our breath to keep from laughing.

If you watch that specific episode today, you can see that our shivering looks incredibly authentic.

We weren’t shivering from the cold.

We were shaking from the sheer, agonizing effort of trying to hold in our laughter.

That moment became a legendary story on the set.

Whenever the days got too long or the scripts got too heavy, someone would just look at Wayne and whisper the punchline.

It was the perfect reminder of how ridiculous our jobs really were.

We were grown adults, dressing up in costumes, pretending to freeze while actively cooking groceries on our faces in the California sun.

You simply can’t survive an eleven-year television shoot without finding the humor in the misery.

Those absurd, unscripted moments of pure joy were what kept us all going.

Funny how the most miserable day on paper turned into the funniest memory of my career.

Have you ever had a completely miserable situation suddenly turn into an uncontrollable laughing fit?
