Listen a good laugh never killed anyone but this clip from the Carol Burnett Show might come close. It seems they were trying to get through a Mama's Family sketch and Tim Conway begins to tell a ridiculous story about a circus elephant and it goes on and on and becomes more silly and convoluted. Carol Burnett was always stressing how you should never break character and she, well you'll see. They are trying to play Pass Word and Carol's character is supposed to say, "Go on Mama." Stick with it to the end. Vikki Lawrence nails it.
