The 25 Best Episodes of 'Futurama,' According to IMDb

After Professor Farnsworth creates a box with a parallel universe inside it, Leela is sent in, only to discover another Planet Express, creating a box of its own. The clashing delivery crews collide, and ultimately give one another their boxes, protecting their own universes.

In one of the series’ more philosophical episodes, Bender gets lost in space and becomes the god of a colony of tiny living beings who settle on his metallic body. When they ultimately destroy themselves, Bender is left feeling hopeless and alone until he comes across a mass of space dust and twinkling lights claiming to know everything about him.

After Fry eats a roadside egg-salad sandwich, he is infested with worms that make him inexplicably smarter and stronger. As Leela falls for the new and improved Fry, the rest of the crew travel through his body to dispel the worms from his system, and Leela must decide which Fry she cares more about.

Traveling back in time to Roswell, New Mexico, in 1947, Fry and the gang are involved in a series of historical hijinks, including Dr. Zoidberg being researched by scientists, Bender being mistaken for a UFO, and Fry accidentally killing his grandfather and becoming his own grandfather after falling for his grandmother.

After going on a mission which causes the deaths of the previous Planet Express crew, Fry is stabbed through the chest by a giant bee, and seemingly dies. As Leela mourns him, she dreams of him night after night and feels like she is going crazy. It’s revealed in a sweet-as-honey twist at the end of the episode that Leela is the one who got stung, and has been in a coma all this time, while Fry has been at her bedside day-in and day-out.
