The duo had the audience in stitches as Harvey Korman played a nervous patient and Conway played the role of the dentist.

Tim Conway reveals joke that made Harvey Korman wet his pants on ‘The Carol Burnett Show’
They don’t make comedians like Tim Conway and Harvey Korman anymore. The duo was a laugh riot every time they were on screen, and the best example of that was “The Dentist” sketch on “The Carol Burnett Show.” Conway revealed to Conan O’Brien that Korman wet his pants from laughing. Conway played the role of the dentist while Korman played a nervous patient who had the audience in stitches. The sketch starts with Korman arriving at the dentist’s place to find out that the regular dentist isn’t available. The nurse insists the new dentist is qualified, but adds that he just graduated.

Conway is equally, if not more, nervous about attending to a patient. He musters the courage and decides to pull out Korman’s tooth as requested. What follows is a comedy of errors, starting with the incompetent dentist sticking the novocaine needle into his own skin, briefly paralyzing his right hand. Conway insists on going through with the procedure, and Korman begs to be relieved of his toothache. Conway then accidentally jabs his right foot and is comically trying to go through with the procedure with a briefly paralyzed right hand and foot. Halfway through the sketch, Korman can’t hold a straight face anymore and starts to laugh. He has simply given up as he watches Conway deliver a lesson in physical comedy. The audience is roaring with laughter throughout the sketch.
