In this Conan O'Brien-penned episode, Mr. Burns is forced to pay a fine of several million dollars to the City of Springfield for his illegal toxic waste dumping, and the residents have to decide what to do with their windfall. At first, Marge's suggestion of repairing the severely damaged Main Street looks to be the one honored, but that's when out-of-towner Lyle Lanley steps in and uses a catchy song-and-dance number to hornswoggle the town into shelling out for an expensive monorail system instead.
