WALL•E is a trash compacting robot.
Homer meets WALL•E 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.
He is seen again during the montage when Nikki was giving Bart CPR, he is seen getting kissed by EVE.
He later holds a gun to Lisa before the Golden Globe awards.
