Tim Conway plays a recently graduated dentist on his very first day treating patients. He accidentally injects himself with novocaine while trying to give his first patient (Harvey Korman) a shot, causing his mouth and hands to go numb. Conway's physical comedy as he struggles with the effects of the novocaine while attempting dental procedures creates increasing anxiety for Korman's nervous patient character. This sketch is widely considered one of the most beloved and memorable sketches from The Carol Burnett Show, famous for Conway's improvised physical comedy that frequently broke Harvey Korman's character, causing him to laugh uncontrollably.
