The Kramdens' apartment is going to pot--the pipes leak, the walls are cracking, the sink won't work, doorknobs are falling off. Ralph is fed up, so he seeks out Shaughnessy, the neighborhood lawyer, who advises him to withhold his rent until the landlord makes repairs. Ralph decides to take the rent money and repair and redecorate the apartment himself. He buys a new bathtub, and wallpaper that is too gaudy even for Norton (Alice describes it as "early Halloween"). Ralph papers the apartment, but soon thereafter a painter comes in and undoes the damage. Finally comes the confrontation with the landlord. Ralph rails at him for being a cheapskate and a tightwad, and tells him that a clause in his lease allows him to withhold rent money and use it for repairs. The landlord tells Ralph that another clause in the lease allows the landlord to cancel the lease entirely, and that Ralph is now an ex-tenant. The landlord says he'll renew the lease if Ralph agrees to pay an additional fifteen do (thetvdb.com)
