What a great clip! One of the things that I liked best from the Carol Burnett Show (which 3 of the actors were from) was watching them try not to laugh. The more they tried not to laugh, the funnier it was. It seemed to be a game for them to see who could make the others lose control. Tim Conway and Harvey Korman were the worst when paired together. They just don't make shows as funny as that one was anymore.
