The Computer Wore Menace Shoes - S12-E6
Trivia: Although Homer claims not to have a computer, he used one in the episode "King-Size Homer" when he was assigned to work at home due to his hyper-obesity. However, this was installed by (and likely remained the property of) Mr. Burns. In "El Viaje Misterioso de Nuestro Jomer", the "Space Coyote" instructed him to get more possessions, and reminded him that he did not even own a computer. On the other hand, during the meteor shower in "'Scuse Me While I Miss the Sky", Marge makes a reference to a screensaver, implying that they do own a computer ("This is even better than our screensaver. And I love our screensaver.").
Trivia: The techno music that plays when Lisa runs is lifted straight from arty-German film 'Run Lola Run', which this episode directly mimics, in which we follow a race against time in the life of Lola, with three different versions of the day, with subtle differences leading to massive consequences. The music is played while Franka Potente (Lola) runs, as Lisa does.
