Elizabeth Patterson makes her first series appearance as Mrs. Trumbull, the Ricardos' elderly, cranky neighbor. Disturbed by Little Ricky's constant crying, Mrs. Trumbull invokes the "no children" clause in the apartment house's lease and demands that landlady Ethel (Vivian Vance) evict the Ricardos immediately -- adding that if this doesn't happen, Mrs. Trumbull and all the other tenants will themselves move out. Refusing to kowtow to this threat, Ethel loyally stands by her pal Lucy (Lucille Ball): "My friendship with the Ricardos means more to me than all the money in the world!" Well and good -- but then Ethel proceeds to repeat the story of her loyalty, over and over and over again, to anyone who will listen (and a few who won't!). Ultimately, Lucy gets fed up with Ethel's "nobility" and tells her off -- whereupon World War III erupts between the Ricardos and the Mertzes.
