In-A-Gadda-Da-Leela

[1] In the episode, Zapp Brannigan and Leela end up on a Garden of Eden-like world after fighting a planet-destroying satellite called V-Giny.

After running several simulations, he realizes that the death sphere is the result of a collision between two artificial satellites that were launched into Earth's orbit in 1998.

Zapp Brannigan and Leela are sent to destroy the death sphere in an undetectable one-man craft built by Farnsworth.

Upon confronting the sphere's control center, Leela utters "holy cr—", triggering the censor, which sends a black, crude oil-like substance towards them.

In the meantime, the Planet Express crew travels to Lo'ihi Island in Hawaii, the one spot where humanity has not made its mark.

Brannigan tries to bargain his way out due to the uncomfortable setting but Leela forces him into it, which causes Fry a great deal of grief, and he begs for it to be censored.

This episode had to be toned down when it aired on Sinclair Broadcasting affiliates, but it still kept a TV-14 rating for suggestive dialogue (D), offensive language (L), sexual situations (S), and violence (V).

It is also a reference to the Star Trek: The Original Series episodes "The Changeling" (in reference to the fact that the V-chip and the USAF Flying Destiny colliding like the Nomad probe) and "The Doomsday Machine" (an ancient military starship that has gone rogue and destroyed several planets, before heading toward the Federation).

The movie's antagonist, referred to as the "great evil," is a giant sentient sphere with the ability to communicate with humans on a mission to destroy life, and shares many attributes with Futurama's V-GINY.

The best of the old episodes always had a touch of something that spoke out about something (i.e. global warming in 'Crimes of the Hot,' environmental awareness in 'A Big Piece of Garbage').
