The studio lights were always a bit too bright for an old stage actor like me, but sitting across from a friendly face in a late-night talk show chair made it feel a bit more like home.

The host leaned forward, a mischievous glint in his eye, and reached under his desk.

He pulled out a small, white pastry box, the kind you’d find at a high-end bakery in Beverly Hills.

He set it on the table between us and opened the lid to reveal a single, perfect piece of chocolate cake topped with a mountain of whipped cream and a bright red cherry.

I couldn’t help it. I let out that deep, rumbling belly laugh that the fans always seemed to love.

“Oh, no,” I said, waving a hand at the cake. “You are trying to bribe the guard. I see nothing! I hear nothing! I eat… well, maybe I eat a little bit.”

The audience roared, and as the laughter died down, I felt that familiar warmth of a memory bubbling up to the surface.

“You know,” I told the host, leaning in as if sharing a secret with the millions watching at home, “people always ask if the food on Hogan’s Heroes was real.

Most of the time, Robert Clary—our wonderful LeBeau—would make sure there was something edible on the table because he knew I was a man of, shall we say, healthy appetites.

But there was one afternoon during the second season, on a day that was pushing a hundred degrees on the Desilu backlot, where my stomach got the better of my professional training.

We were filming a scene where Hogan and the boys were supposedly smuggling a secret underground map out of the camp by hiding it inside a massive, three-tier Black Forest cake.

My job was simple: walk into the barracks, smell the air, find the cake, and then be ‘convinced’ to look the other way in exchange for a slice.

The problem was that I had skipped lunch that day for a wardrobe fitting.

I was ravenous, and that cake looked absolutely magnificent under the studio lights.

Our director, Gene Reynolds, was in a hurry because we were losing the light, and he kept shouting for everyone to get into position.

The prop master, a lovely man who usually took great care of us, gave me a quick wink before we started.

I didn’t think twice about it.

I was just focused on the smell of chocolate and the growl in my gut.

Gene called out, ‘Action!’ and I marched into that barracks with all the mock-authority I could muster.”

I saw the cake sitting right there on the center table, surrounded by Bob Crane, Richard Dawson, and Larry Hovis.

They were all looking at me with those suspicious, guilty faces they did so well.

I was supposed to do a bit of a dance, sniffing the air like a bloodhound, but I was so hungry I just went straight for the target.

I loomed over them, my shadow falling across the frosting, and I didn’t even wait for Bob to offer me the bribe.

I just reached out, grabbed a massive hunk of that cake with my bare hand, and shoved it into my mouth before Gene could even call for the next line of dialogue.

The moment the ‘cake’ hit my tongue, the world stopped.

It wasn’t chocolate. It wasn’t even food.

The prop department, worried about the cake melting in the extreme heat of the barracks set, had constructed a ‘hero’ prop for the wide shots.

The interior was a solid block of industrial-grade styrofoam.

The ‘frosting’ was a thick layer of white shaving cream mixed with a heavy-duty lacquer to give it a permanent, glossy shine.

And the ‘chocolate’ shavings? Those were actually bits of dark brown felt glued onto the lacquer.

My mouth was suddenly filled with the taste of chemicals, soap, and dry, scratchy foam.

I couldn’t swallow, and I certainly couldn’t spit it out—not while the cameras were rolling and Gene was finally getting the ‘perfect’ take he wanted.

I stood there, frozen, with my cheeks bulging like a squirrel that had discovered a cache of poisoned acorns.

Bob Crane realized what had happened almost instantly.

I saw his eyes go wide, then settle into that classic, devious Hogan smirk.

He didn’t call for a cut.

Instead, he leaned in closer, looking me right in the face, and said, ‘Something wrong, Schultz? You look like you’ve finally swallowed a secret you can’t digest.’

Richard Dawson, God bless him, couldn’t help himself.

He leaned over and whispered, ‘Is it a bit dry, John? Would you like a glass of motor oil to wash it down?’

I was turning a shade of purple that I don’t think has a name in the natural world.

My eyes were watering from the soapy sting of the shaving cream.

The crew was silent, but you could feel the vibration of twenty people trying not to explode with laughter.

Gene Reynolds, who was watching on the monitor and hadn’t realized the cake was a fake, was shouting, ‘Keep going! This is great! The physical comedy is gold, John! Give us the line!’

I had one job. I had to say the catchphrase.

I took a deep, shaky breath through my nose, which only served to inhale some of the shaving cream foam into my sinuses.

I looked at the ‘map’ that was supposed to be hidden in the cake—which was actually just a piece of gray cardboard—and I tried to speak.

What came out wasn’t a line of dialogue.

It was a wet, muffled, bubbly gargle that sounded like a drowning tuba.

‘I… thhh… nnn… thhh…’

I tried again, forcing the foam back with my tongue.

‘I SEE NOSS-ING!’ I finally bellowed, and as I did, a giant cloud of white shaving cream suds sprayed out of my mouth like a fire extinguisher, coating the front of Bob Crane’s leather jacket.

The set erupted.

I have never heard a sound like it before or since.

It wasn’t just laughter; it was a total collapse of professional order.

The cameraman actually tipped his rig over because he was doubling over.

Gene Reynolds came running out from behind the curtain, saw the state of my mouth and Bob’s jacket, and just sat down on the floor, put his head in his hands, and shook.

The prop master came running over, white as a sheet, screaming, ‘Don’t swallow it! John, for the love of God, don’t swallow!’

He started handing me towels and a bucket of water, while Richard Dawson was leaning against a bunk, gasping for air, pointing at me and wheezing, ‘He finally did it! Schultz finally ate the evidence!’

It took us two hours to clean up the barracks and get the shaving cream out of the floorboards.

Bob had to change his jacket, and I spent the rest of the afternoon in the infirmary trailer having my mouth rinsed out with something that tasted only slightly better than the foam.

But you know, for the rest of the series, whenever there was a scene involving food, the boys would always wait for me to take the first bite.

They’d lean in, complete silence on the set, and wait to see if I’d spray foam or if I’d actually find a piece of Robert’s strudel.

It became our little ritual.

It reminded us that even in a show about a prisoner-of-war camp, we were really just a bunch of friends playing in a sandbox, occasionally eating the sand by mistake.

I suppose that’s the secret to why we all stayed so close.

We weren’t just actors playing parts; we were a family that could laugh at a man with a mouth full of soap.

I think the world could use a little more of that kind of foolishness today, don’t you?

Do you have a favorite Sergeant Schultz moment that still makes you laugh?
