When Bart stumbles into a burlesque theater tucked away in a creepy old mansion, he begins working there as a doorman and eventually an MC. From his perch at the front of the Maison Derriere, Bart sees everyone from Principal Skinner to his own grandpa coming in for the girls and drinks. But when a group of angry townspeople discover that there's a house of sin in Springfield, they try to shut it down. At a town meeting, the group becomes a frenzied mob that tries to raze the house with trucks and sledgehammers. But when the showgirls, with a little help from Homer, Mayor Quimby, and others, sing a catchy tune about why the place should stay open, the mob backs off.
