Diana stubbornly refuses to join the Christmas spirit, and wears earplugs to try to block out the sound. Meanwhile Tom plays Christmas tunes on the piano (with odd lyrics), wears a Santa suit and generally tries everything he can to get Diana into the spirit of the holiday. Later Tom decides to spread the Christmas spirt to people a little more receptive. He picks up two homeless people and invite them back to Bayview.

Tom and Diana play pranks during the holiday season, one of which injuries Harvey. Harvey ends up slightly altered with a desire to marry Jane. Jane's grandfather visits and might stay. Meanwhile Diana is directing a play about the Nativity, with Tom as the scriptwriter.
