I have the DVD of the first season or two. It's quite hilarious: see the episode mayhem of the mooninites...funniest 15 minutes of animation ever. Also the show has so many classic lines
Meatwad: Do what I say cuz I said it.
Mooninites: Our culture is advanced beyond yours..."
Frylock: Oh yeah? why's that?"
Mooninites: Well for one thing the moon's gravity is one third that of your earth...i don't know if you can understand that but our vertical leap is beyond all measurement"
Frylock: so your culture is more advanced because you can jump higher?"
Mooninites: Yes observe" (jumps maybe an inch, makes old nintendo atari bleep noise which is hilarious) "it's not working"
