When Wednesday's and Pugsley's faith in Santa Claus is shaken, Uncle Fester is chosen to back up Santa. However, Fester-Santa gets stuck in the chimney, so each of the other adults in the house decides to substitute for him.

Because she thinks Fester and Grandmama are spoiling the children, Morticia hires a governess to watch them. Insulted, Fester paints a white line down the centre of the Addams house, dividing it in half.
