The Simpsons: Homer Cubed

In a parody of the Twilight Zone episode, Little Girl Lost, Patty and Selma visit the Simpsons with two pillow cases full of seashells from their trip to "Sulphur Bay" from which they plan to pry hermit crabs. Homer tries to hide in a closet that Bart and Lisa have occupied, but they refuse to leave. After failing to find another hiding spot, Homer, desperate to avoid Patty and Selma, looks behind a bookcase and enters a mysterious new world in which everything is in 3D. (wikipedia)
