“90 MILLION PEOPLE WATCHED IT… AND STILL LAUGH LIKE IT’S THE FIRST TIME.”

“90 MILLION PEOPLE WATCHED IT… AND STILL LAUGH LIKE IT’S THE FIRST TIME.” Tim Conway didn’t need a script to make the world laugh. All he needed was one breath — that quiet pause before he walked into the famous dentist sketch. Harvey Korman tried to stay serious like a professional, but you could see it in his eyes… he never stood a chance. Tim started improvising, slow at first, then wild, until Harvey was shaking so hard he could barely sit in the chair. Carol Burnett was wiping tears, the crew was gone, everyone collapsing behind the cameras. Watching it now, you can still feel that same magic — the kind that only happens when friends make each other laugh for real.

When people talk about the golden age of sketch comedy, the conversation almost always circles back to The Carol Burnett Show. At the center of that legacy stand two comedy legends whose on-screen chemistry remains unmatched: Tim Conway and Harvey Korman. Their scenes together were unforgettable, but one sketch towers above the rest — the chaotic, wildly improvised dentist sketch that became so hilarious, Harvey Korman reportedly laughed so hard he briefly lost control.

This classic moment has resurfaced yet again thanks to a side-splitting interview Tim Conway gave on Conan O’Brien’s talk show, where he recounted the behind-the-scenes truth. What began as a simple premise — Korman as a nervous dental patient and Conway as a clueless, newly trained dentist — quickly unraveled into one of the most iconic on-air meltdowns in television history.

The Chaos That Made Television History

From the instant Conway stepped into the scene, Korman was already trying not to burst out laughing. The setup was straightforward: Conway’s inexperienced dentist had never worked on a real patient before, and in his panic, he accidentally numbed himself with novocaine — first his hand, then his leg, and finally half his face.

None of the physical comedy that followed was scripted. Conway improvised nearly every ridiculous movement, and Korman, fighting to stay in character, crumbled bit by bit. During his interview with Conan, Conway revealed that Korman was laughing so uncontrollably — gasping for air, unable to speak — that filming had to be paused. And yes, according to Conway and later accounts, Korman truly did laugh himself into a momentary accident.

Why This Sketch Still Matters

This story isn’t just comedy lore — it’s a perfect example of what made live sketch comedy feel so electric. The dentist sketch embodies:

The raw unpredictability of live television — where the best jokes weren’t planned.
The brilliance of improvisation — Conway’s creativity pushing Korman past the point of composure.
Their remarkable partnership — built on trust, timing, and genuine joy in each other’s reactions.
The timeless joy of real, uncontrollable laughter — the kind that still resonates decades later.

Fans today describe the sketch as the moment when “the king of improvisation finally broke the king of composure.” New audiences discovering the viral clip are realizing what longtime viewers already knew: whenever Conway and Korman shared a scene, magic was almost guaranteed.

Comedy That Never Ages

The clip continues to circulate because it still delivers the same pure delight it did in the late ’60s. It feels authentic — two friends trying to keep a straight face while the entire world watches them fall apart. No special effects, no manufactured shock value. Just two masters of their craft having fun and letting the moment carry them.

Even today, the dentist sketch stands as one of television’s most genuine comedic treasures — a reminder that sometimes the best laughs come from the accidents no one ever meant to happen.
