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 that 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.
