Soylent Green

The first appearance of Soylent Green was way back in the episode Itchy and Scratchy the movie. When Bart was banned to c it he waited for up to 40 years and when him and Homer went they came across a man at the food counter, Who asked for Soylent Green with Butter. Homer then said to himself 'mmmm....Soylent Green'

Erm...actually the first appearance of Soylent Green is in the cult movie "Soylent Green", not from The Simpsons. Soylent Green is a food stuff that was made from people, hence the line "Soylent Green...It's people!"
The Simpsons and Futurama are both parodying it.

Edit: And we already have a Simpsons / Futurama thread , in the Weird Scenes section...

And the Decapodean national anthem is actually the fight music from the old Star Trek.  The fighting is based on a fight between Kirk and Spock in an episode called "Amok Time" (of which the entire episode "Why Must I be a Crustacean in Love" is a parody).

Way to prove your own ignorance of things barely even thirty years old, raybow.
