It is funny how a single sound can just transport you back forty or fifty years in an instant.

I was sitting in this little studio in Los Angeles for a podcast a few years back, and the host, this young guy who clearly grew up watching the reruns, brought up the famous blooper reels.

He mentioned that legendary clip of the tunnel entrance in the bunkhouse sticking, and suddenly, I wasn’t in a climate-controlled studio anymore.

I was back in 1967, smelling the sawdust and the stale coffee of Stage 4 at Desilu.

We were filming an episode where the whole gang—me, Bob, Larry, Robert, and the big man, John Banner—had to be crammed into that tiny underground set for a high-stakes meeting.

Now, you have to understand that the tunnel set was not some architectural marvel.

It was mostly plywood, Styrofoam, and a lot of hope, held together by the best scenic artists in the business, but it was incredibly tight.

On this particular Tuesday, we were all a bit on edge because we were behind schedule, and the director was leaning on us to get this one long, dramatic tracking shot in the “secret” headquarters.

The lighting was particularly hot that day, and when you get five or six grown men in wool uniforms under those lamps in a confined space, things get a bit ripe.

Bob Crane was trying to keep us focused, doing that trademark Hogan “serious face” while he moved a pointer across a map.

John Banner, God bless him, was standing right at the edge of the frame, supposed to be keeping watch, but he was struggling because he’d had a particularly large lunch and the “tunnel” was feeling about six inches narrower than it had that morning.

We were right in the middle of this tense dialogue about smuggling a defecting general out of Germany, and the atmosphere was actually quite heavy for a comedy.

I remember thinking that we were finally nailing the “drama” part of the “dramedy.”

Then, I heard this very distinct, very ominous creaking sound coming from the wall right behind John’s left shoulder.

The entire “reinforced earth” wall of the secret Allied headquarters simply decided it had seen enough of show business.

It didn’t just fall; it sighed.

The plywood groaned, the Styrofoam buckled, and a massive section of the tunnel wall collapsed outward, revealing the absolute chaos of the backstage area.

Now, you have to picture the scene.

One second, we are elite commandos in a high-stakes underground bunker in Nazi Germany.

The next second, we are five actors staring through a gaping hole at a craft service table where a bewildered grip was halfway through a ham sandwich.

The silence that followed was heavy, but it only lasted for about three seconds.

John Banner, who was the closest to the disaster, didn’t even move at first.

He just stood there with his rifle, looking through the hole at the grip with the sandwich, and in that perfect, booming Schultz voice, he just whispered, “I… I really see nothing now.”

That was the end of it.

Bob Crane went down first.

He just doubled over, leaning his head against the map of the Rhine, and started making these high-pitched wheezing sounds that meant he’d lost all respiratory control.

Then Robert Clary started chirping in French, which he only did when he was truly hysterical, and I just sat on a crate and put my face in my hands.

The director, who had been so stressed about the schedule five minutes ago, just threw his headset onto his chair and walked away, shaking his head.

He knew the day was over.

But the real comedy came when we tried to get John Banner out of the wreckage.

Because the wall had collapsed at an angle, it had wedged itself against the “bunks” we used for the tunnel scenes, and John was effectively pinned in a small triangle of fake dirt.

He wasn’t hurt, mind you, he was just too large to maneuver through the gap.

Every time we tried to pull him out, another piece of the set would start to groan, and we’d all have to back off and start laughing all over again.

The crew was eventually in tears, the lighting guys were leaning over the catwalks pointing and shouting suggestions, and the poor grip who had been seen through the wall just stayed there, frozen, holding his sandwich like a holy relic.

It took twenty minutes just to get the laughter down to a level where we could actually talk.

We spent the rest of the afternoon watching the carpenters try to rebuild the Third Reich with duct tape and staples.

Every time they hammered a nail, someone would yell out an “I know nothing!” from the back of the stage, and we’d lose another ten minutes to the giggles.

It’s moments like that where you realize why the show worked.

We were playing in a very strange, dark sandbox, given the subject matter, but we were a family of idiots who genuinely loved the absurdity of it all.

When you spend twelve hours a day in a fake prison camp, you either find the humor in a collapsing wall or you go completely mad.

I think we chose the better option.

Looking back on it now, sitting in that podcast booth, I realized that the “chaos” was actually the glue that held us together for six years.

People ask if we ever got tired of the uniforms or the repetitive sets, and I tell them no, because you never knew when the set was going to decide to join the comedy routine.

It reminded me that no matter how serious you think your “art” is, there is always a wall waiting to fall down and show you a guy eating a ham sandwich.

That is the best lesson a performer can ever learn.

Does your workplace ever have those moments where everything falls apart and all you can do is laugh?
