19. Smithers' Start-Up Screen - "Lisa Vs. Malibu Stacy" (5.4)
Smithers' obsession with his boss, Mr. Burns, has been well documented over the years. A well-kept secret generally, nobody can forget that moment where he switches on his computer with Lisa by his side, only to reveal his start-up screen as a nude, pixelated Burns: "Hello, Smithers. You're quite good at turning me on." This felt rather risque at the time, with that image of a naked Mr. Burns forever burned into your eyeballs.
