The Professor's "What-If" machine simulates Bender, Leela and Fry's wishes. Bender discovers what it would be like if he were 500 feet tall, Leela discovers what it would be like if she were more impulsive, and Fry discovers what would happen if he never came to the future.

Futurama is reconceived in three alternate animation styles: classic black-and-white, old-school videogame, and Japanese anime.
