Gus' Dad May Have Killed an Old Guy

It's Christmastime and the Gusters have invited Shawn and Henry over for dinner, one of only a handful of such invitations ever extended to the Spencers since Bill and Winnie Guster have always thought of Shawn as a bad influence on their son. After their meal, during which Shawn tries to prove he's actually been a help to Gus over the years, the group goes caroling through the old neighborhood, starting with everyone's most hated neighbor - Old Man Fuller. But when they get up to the house, Shawn knocks on the front door, which swings open to reveal Fuller, hanging from the banister.
