Plot summary
Hal and the boys spend the day at a bridal exposition (which Hal had mistaken for a car exposition). Reese is lent a tuxedo by a vendor; he enjoys how much nicer he is treated so much that he refuses to return it. Dewey enlists several people at the convention to humiliate Hal by publicly announcing that the baby's planned delivery date is his birthday. Malcolm has been accepted to a prestigious boarding school in England, but Hal forbids him to go because the family cannot function without him. Ida moves in after her apartment burns down and she refuses to stay with Susan.
Knowing that Ida has a fear of black people, Francis, Lois, and Piama enlist Abe and his poker buddies to help scare Ida out of the house, but she decides to stay when Lois' water breaks. Upon receiving a phone call from Lois, Hal and the boys rush to the car park, but they are detained by security for prior offenses.
