Arthur has purchased a new Armoire, and wants to use Doug's delivery truck to get it home. Doug refuses, but somehow ends up making the delivery anyway. After listening to endless complaints from Arthur, Doug finally loses control and he and Arthur have a big fight. Arthur offers to move out of the house, and into his own apartment. Carrie is concerned that Arthur won't be able to survive living on his own, but after a visit to his house-warming party, she and Doug discover that his apartment is swankier than their house. They soon find out that Arthur is in over his head when he comes back asking to borrow money in order to pay his very high monthly rent. Before long, Doug has forgiven him, and he is settled back in the basement of the house.
