During a recent podcast interview, the host threw a curveball at Alan Alda. They had been discussing the deep emotional weight of the show and its lasting legacy.

But then, the host casually asked if there was ever a co-star who was utterly impossible to work with on set.

Alan leaned into the microphone, a slow, knowing smile spreading across his face. He didn’t even have to think about it.

He just nodded and told the host that the most difficult actor they ever worked with wasn’t a human. It was a pig.

He transported listeners back to 1974, deep in the mountains of Malibu Creek State Park.

The cast and crew were filming a beloved third-season episode outside in the compound, far away from the medical clinic.

The camp was preparing to host a traditional Greek Easter feast, complete with a live pig destined for the roasting spit.

Naturally, the soft-hearted Radar O’Reilly, played brilliantly by Gary Burghoff, takes it upon himself to save the animal’s life.

Alan described the miserable filming conditions that day. The California sun was beating down on the outdoor set.

The ground was nothing but dry, choking dust. The cast was exhausted, sweating heavily in their thick olive-drab uniforms.

The animal handler proudly brought the pig onto the set near the mess tent.

He assured the director, the exhausted crew, and the nervous cast that this animal was a consummate professional.

It was highly trained, completely docile, and guaranteed to hit its mark without any trouble.

They quickly set up the cameras. Gary got into his starting position.

The entire crew stood by in quiet anticipation, just wanting to finish the scene.

The director finally called for action.

All the pig had to do was stand perfectly still for ten seconds while Gary delivered his earnest, heartfelt dialogue.

The tension on the set was thick. Everyone held their breath, praying the animal would cooperate so they could retreat to the shade.

And that is exactly when it happened.

The pig absolutely did not hit its mark.

Instead, it looked around the set, seemed to realize that forty humans were staring at it, and immediately decided it was time to leave.

With an explosive burst of speed that defied logic, the supposedly docile pig bolted.

It darted right between Gary Burghoff’s legs, nearly taking the actor down into the thick Malibu dust.

The professional animal handler lunged forward in a panic to grab the tether.

He missed entirely, diving face-first into the dirt while the pig executed a flawless evasive maneuver.

For a split second, there was total silence on the set.

Then, absolute pandemonium erupted as every single person broke character at the exact same time.

Alan recalled standing near the mess tent, completely losing his composure.

He doubled over, laughing so hard that no sound came out. The sheer absurdity of the moment washed over the entire cast.

The director yelled to cut the cameras, but nobody could hear him over the commotion.

The camera crew was laughing so violently that the heavy equipment began to visibly shake.

They accidentally captured blurry, chaotic footage of a rogue farm animal taking over a military camp.

McLean Stevenson, always eager for a bit of physical comedy, decided he was going to be the hero of the day.

He broke from the group, sprinting after the pig with his famous fishing bucket hat flying off his head.

McLean attempted a spectacular, diving tackle to corral the beast.

He ended up sliding through the dirt, coming up completely empty-handed and covered in a thick layer of brown dust while the pig trotted casually past him.

By this point, filming had completely halted.

It was no longer a prestigious television production. It was a chaotic game of tag between a cast of award-winning actors and a stubbornly fast pig.

Gary was still chasing his runaway co-star, jokingly yelling out his lines in a desperate attempt to somehow save the ruined take.

Wayne Rogers tried to flank the animal from the left, waving his arms like he was directing traffic.

That sudden movement only seemed to encourage the pig to run even faster toward the production vehicles.

The sound technicians simply gave up.

They dropped their heavy boom mics into the dirt and leaned against the supply trucks, crying literal tears of laughter.

The mistake quickly evolved into a legendary running joke among the crew.

The pig somehow navigated the complex labyrinth of canvas tents, props, and lighting stands with the agility of a professional athlete.

The animal finally realized exactly where it wanted to go.

It completely bypassed the officers’ quarters and made a direct, unstoppable line for the one place on set that actually mattered.

The craft services table.

Alan vividly described the hilarious sight of the cast and crew finally catching up to the fugitive, only to find it happily rummaging through the catered crew lunch.

Loretta Swit had wisely retreated to the safety of her canvas chair, watching the entire spectacle unfold from a very safe distance.

Meanwhile, Larry Linville somehow managed to stay completely in character.

He stood there glaring at the chewing pig with that trademark Frank Burns look of utter disgust, which only made Alan and Wayne laugh even harder.

It took the crew nearly two hours to finally calm the set down and secure the perimeter.

But even then, the damage to the filming schedule was completely done.

Every time the director tried to reset the scene, someone would look at the thick dirt smudges on McLean’s uniform and burst into laughter all over again.

Multiple retakes failed purely because the cast could not keep straight faces while looking at the animal.

The pig had firmly established dominance over the entire Hollywood production, and everyone on set knew it.

Alan noted that the episode eventually turned out beautifully, becoming a massive fan favorite.

But behind that touching story of Radar saving a doomed animal was the hilarious reality of a completely ruined afternoon of filming.

It remains one of his favorite memories from his entire time on the legendary show.

It was a perfect reminder that no matter how serious the dialogue or how tight the shooting schedule is, sometimes you just have to surrender to the unpredictable chaos of life.

Filming a television show is a massive, highly stressful undertaking, but moments like that keep the humanity intact.

When a rogue farm animal entirely shuts down a multi-million dollar Hollywood production, you have absolutely no choice but to stop, take a breath, and laugh at the pure absurdity of the situation.

It was exactly that kind of spontaneous joy and shared ridiculousness that helped bind that cast together for over a decade.

Have you ever experienced a completely chaotic moment at work where everything went so wrong that you couldn’t help but laugh?
