S1·E13 The Spare

The Hartmans' hopes of beating the Balduccis in a bowling tournament go down the gutter when teammate Sally hurts her back -- but it only gets worse when Elizabeth replaces her. After Sally, an excellent bowler on Kirk's team, hurts her back, Kirk gets Elizabeth to replace her. Unfortunately, he soon realizes that Elizabeth is a terrible bowler. When the team asks Kirk to terminate Elizabeth, Kirk must choose between possibly winning the league championship or being unkind to Elizabeth.
