"The Carol Burnett Show" ran from 1967 to 1978 and has been touted as one of the best television series of all time. The cast and guest stars of the show included comedic greats such as Tim Conway, Betty White, Steve Martin, Vicki Lawrence, Dick Van Dyke, Lyle Waggoner, Harvey Korman and others who went on to have long, successful comedy careers.

One firm rule Carol Burnett had on her show was that the actors stay in character. She felt it was especially important not to break character during the "Family" scenes, in which the characters Ed and Eunice Higgins (a married couple) and Mama (Eunice's mother) would play host to various colorful characters in their home.

"I never wanted to stop and do a retake, because I like our show to be ‘live,’" she wrote in her memoir, as reported by Showbiz Cheat Sheet. "So when the ‘Family’ sketches came along, I was adamant that we never break up in those scenes, because Eunice, Ed, and Mama were, in an odd way, sacred to me. They were real people in real situations, some of which were as sad and pitiful as they were funny, and I didn’t want any of us to break the fourth wall and be out of character.”

It was a noble goal, and one that went right out the window—with Burnett leading the way—in a "Family" sketch during the show's final season that ended with the entire cast rolling with laughter.
