Last week or so was an American Masters program on PBS featuring Carol Burnett and her rise to fame and the show and whatnot. The program did a good job of charting the comedic gold of her talents and the rest of the cast that made that show so funny for 11 YEARS. The only thing the show left out was Tim Conway's Elephant story lifted from a Mama's Family sketch that put the cast on the floor. I remember seeing this spot on TV and my whole family laughing for 20 minutes after. What was odd was how the program even seemed to lead right up to this sketch talking about how Tim would riff on something and loved to get the cast to break up. This is the ultimate in comedic timing and Ad Lib.
