Arthur's Inheritance - S1.E11

A telegram arrives one evening for Arthur, and after some hesitation he opens it to learn that his rich, 93 year-old Uncle Elroy from Montana has died and left him something. Stanley insists that Arthur call the lawyer to learn what he is to inherit. Arthur initially tries to hide that he's supposed to receive $20,000 from his uncle's estate. This gives Stanley visions of being able to recapture some of Arthur's expenses that he's paid over the years -- but it turns out that the inheritance comes with a catch.
