Burns' Summer Mansion

Burns' Summer Mansion is a mansion where the Simpson family lived for a period of time.

History
Eccentric documentary filmmaker Declan Desmond offers an inside look at his work chronicling some of Springfield's finest for his documentary. Titled "Growing Up Springfield", his film follows the lives of several Springfield residents, returning to them after eight-year intervals to examine how their lives have changed. When he returns in the present day, he discovers that Homer has become extraordinarily wealthy, and the family is living in the mansion.

Homer explains that his newfound wealth is due to an invention called the condiment pen, which dispenses condiments in the same manner as a writing pen dispenses ink. Declan interviews Marge about her family's unexpected success, but she is unable to explain why the mansion's medicine cabinet is filled with "old man ointments." Suddenly, Mr. Burns bursts into the house, demanding to know what the Simpsons are doing in his summer home.

The summer mansion is located in Middle Hampton, and is where "Monogram Monty" Burns used to throw parties during his younger days. He grew depressed and threw another party to relive his youth. The party ended badly, and Homer and Mr. Burns crashed a party hosted by billionaire music tycoon Jay G, who was inspired by Burns in his book, The Rungs of Ruthlessness. At the end of the episode, Jay G bankrupts Mr. Burns and repossesses all of Burns's possessions, including his summer house. Later, Mr. Burns is forced to relocate to his family mausoleum, due to his summer mansion being taken over and sold by Jay G's real estate company. Later, Mr. Burns (presumably) tries to cook Goosius, Jay G's mascot, at this mansion. Eventually, Jay G gives Mr. Burns his summer mansion back in the end.
