This contest will determine the ultimate, most prolific sitcom actor of all time. Each round matches two pairs of actors, two men and two women, in order of when they were most active on television, beginning with the 1950s and going up to the 2000s. In the championship round, the winning man and woman will face each other to determine the ultimate sitcom actor. Starting today, I’ll post one round per day leading up to the ultimate championship round.
