WALL-E
Wikisimpsons - The Simpsons Wiki
WALL-E is a Disney/Pixar trash compacting robot that is left behind on Earth 700 years in the future when all humans leave on a spaceship so they do not have to deal with Earth's problems.
Homer meets WALL-E in "The Burns and the Bees" when he has a thought of what the Earth would be like without honey, and it looks exactly the same as it does in the movie.
