My Occasional Brother's Keeper

During Greta's party in Peter's apartment Mr. Brahms calls and talks to ""Greta's boyfriend"". Greta tells Mr. Brahms it was Peter's brother playing a joke. In honor of Peter's brother being in town the Brahms' invite the three of them over for dinner. Peter hires his milkman Teddy, who is tired of his job, to play his brother. They pass him off as a writer who is leaving on a tramp steamer in the morning. Mr. Brahms offers Teddy a job to keep Peter's family together. Teddy accepts and then Peter and Greta conspire to drive him out of Peter's apartment by convincing him Peter is a little insane and dangerous. Mr. Brahms complains the next day that Teddy quit and took two of his secretaries with him. Peter replies that it's a burden he's had to live with all his life.
