La Maison Derrière
Wikisimpsons - The Simpsons Wiki
The house was once damaged by Nelson while playing outside with Milhouse's model airplane. The house was rumored to belong to a witch, though some (Ralph) claimed a "Frankenstein" lived there and others (Milhouse) believed it was the home of an evil scientist who creates a race of "super-zombies". The kids rang the doorbell on the property's gate and a pre-recorded voice said "go away, no children" while a robot arm of an old lady partly pulled back the house's curtain. Bart ventured onto the property of the house. He climbed onto the roof to retrieve the model airplane but slipped and fell after performing a dance while spelling the word success.
Bart's fall got the attention of Belle, the property's owner. She took him to Homer and he agreed Bart working there. When Bart arrived at the house he saw gambling, drinking and a burlesque show and exclaims to Belle that he had been wrongly informed about witches. Bart eventually takes on a number of odd jobs around Maison Derrière, including taking over as M.C. one evening.
Marge, Reverend Lovejoy, Flanders and other people called a town meeting where Marge incited the town's citizens to form an angry mob which mob then flocked to the house to try to bulldoze it to the ground.
Maison Derrière was fortunately saved (at least in part) after Homer led the townfolk in the song "We Put the Spring in Springfield", which revealed that a lot of prominent townspeople frequented the house. However, a still-zealous Marge, who missed the song, damaged the mansion by running into it with a bulldozer and had to work for Belle to pay for the damage. Marge's first job for the La Maison Derrière was acting as a Ventriloquist, although her act was a bit too "wooden", causing Homer to heckle her by shouting "Take it off" and Bart, acting as a bouncer, escorting Homer Simpson off of the premises.
Among the people who often go the mansion are:
Even though Belle called it a place where she provides cheeky, fun entertainment for men, some female patrons (besides Patty) are seen. Some may be prostitutes, in Belle's employ, on a date, or simply there to get a drink.
