painting of a boat hangs on the wall above the living room couch. Marge says she painted it for Homer in "The Trouble with Trillions". In the episode "Diatribe of a Mad Housewife", the painting has a plaque saying it was based on a scene from Moby Dick. In the Season 27 episode "Barthood", young Lisa is seen drawing the sail boat painting. In the episode "Homer and Ned's Hail Mary Pass", Homer destroys the painting over the couch and Marge retrieves a replica out of a closet. The painting is also destroyed by Lisa's guinea pig in "The War of Art" but it gets replaced with a replica made by a famous art forger. In the "Treehouse of Horror IV" episode, the Dogs Playing Poker painting appears above the sofa. In "Treehouse of Horror VI", there is a portal behind the bookcase in the sitting room that leads to the third dimension, a reference to The Twilight Zone episode "Little Girl Lost". However, Treehouse of Horror episodes are not canonical. Condition The house is often shown as dilapidated. For example, the walls are painted with lead paint and the roof leaks. In "All's Fair in Oven War", the kitchen receives an extensive modern remodel, but reverts to its previous appearance in the following episode. One running gag shows the interior of the walls and floors filled with dangerous or unusual items when the camera pans between floors or rooms. Some of these unusual items include: asbestos, toxic waste, hidden treasure, recording devices, baby dinosaurs, dancing mice and the family cat, Snowball II. However, the lived-in spaces are usually kept neat by Marge. In one episode Moe Szyslak observes that it contains no silverfish. Many episodes in which Springfield is hit by extreme heat waves indicate that the house lacks air conditioning. In a flashback episode, Homer steals Ned Flanders' air conditioner and puts it in the window. The house is shown to have a gas furnace, as well as a gas stove, water heater, and dryer. In "Days of Wine and D'oh'ses", Homer reroutes the gas line to turn a totem pole into a fire-breathing "god," filling the entire house with gas in the process. Real-life version A replica of the house was constructed in 1997 by California-based Kaufman and Broad homebuilders at 712 Red Bark Lane in Henderson, Nevada. The house was designed to closely mimic the design
