The Moment TV Completely Lost Control: How Tim Conway Broke Harvey Korman—and Made Comedy History

There are funny TV moments… and then there are can’t-breathe, tears-streaming, history-making moments that live forever.
One of the greatest belongs to The Carol Burnett Show, when Tim Conway single-handedly destroyed any hope of professionalism from Harvey Korman—and the audience loved every second of it.
Decades later, fans still talk about that sketch. The one where everything went wrong. The one no one could recover from. The one that proved live television can be absolute magic when chaos takes over.
The Setup Was Simple—The Disaster Was Not
The now-legendary “Dentist Sketch” started innocently enough. Conway played a nervous dentist treating Korman’s patient. The joke? Conway’s character accidentally injects himself with Novocain.
That should’ve been the punchline.
It wasn’t.
Instead, Conway did what he did best—he improvised like a mad genius. His arm suddenly went limp. Then his leg stopped working. His face froze into a bizarre, half-paralyzed expression that looked more cartoon than human. None of it was in the script.
And Harvey Korman? He saw it all coming.
“You Could See Him Shaking”

Conway later admitted he knew the exact moment he had won. He said you could actually see Harvey physically shaking, desperately trying to hold it together. His lips trembled. His eyes watered. His body betrayed him.
Then it happened.
Harvey Korman completely broke.
Once he lost control, there was no coming back. The audience exploded. Laughter rolled through the studio like a wave. It was so loud it nearly drowned out the microphones.
Even Carol Burnett Couldn’t Handle It
As if Harvey losing it wasn’t enough, Carol Burnett herself had to run offstage just to avoid collapsing in laughter. When the person hosting the show can’t stay onstage, you know something legendary is happening.
This wasn’t a mistake.
It wasn’t a blooper.
It was pure, unscripted brilliance.
Why This Moment Still Hits So Hard

What makes the Dentist Sketch timeless isn’t just how funny it is—it’s why it’s funny. You’re watching real people lose control in real time. No edits. No retakes. No safety net.
It’s Conway pushing just far enough.
Korman fighting a losing battle.
Burnett surrendering to the moment.
And an audience lucky enough to witness lightning strike live television.
Comedy That Can Never Be Recreated
Today’s TV is polished. Edited. Controlled.
Moments like this? They can’t be manufactured.
That’s why people still share this clip. Still talk about it. Still laugh like it’s the first time. Because when Tim Conway and Harvey Korman shared a stage, even the script didn’t stand a chance.
