The Simpsons - S14E16: 'Scuse Me While I Miss the Sky

What's the Story?

A snobby British filmmaker named Declan Desmond begins making a documentary about student life at Springfield Elementary School. When introduced to Lisa, he tells her that she has too many goals and suggests that she pick one career. Lisa focuses on astronomy, but cannot watch the stars because of light pollution. She convinces Mayor Quimby to decrease the light's intensity during the night, which only results in an increase in the crime rate. Quimby bows to public pressure and switches the lights back on permanently. Lisa overloads the generators at the Power Plant, causing a power outage, and is able to watch a meteor shower undisturbed by light.
