In the 1973–74 season, the "Family" sketches (with Burnett as Eunice, Korman as her husband Ed, and Lawrence as Eunice's mother) were introduced and the "Carol and Sis" segments were phased out. At the end of that season (the series' seventh), after having been with "The Carol Burnett Show" from the beginning, Lyle Waggoner left the series to pursue other acting opportunities. The following season, Waggoner's spot as a supporting regular remained vacant. Don Crichton, the lead male dancer on the show, began to inherit some of Waggoner's duties. Then in season nine, because of his many popular guest appearances on the series, Tim Conway was signed as a full-time regular, joining Korman and Lawrence.
