Doug tries to reunite Arthur with his estranged half-brother after learning that the two of them own a nearby house, which was left to them by a relative 10 years before. Doug sees this as a great chance to finally get Arthur to move out, but Carrie doesn't think it is such a good idea.

Doug's plan to get the fatty foods he wants to eat through Arthur backfires when Carrie catches on and puts her dad on a strict diet. Meanwhile, Spence camps out in front of a movie theater in order to be the first person in line for an upcoming sci-fi picture.
