I just love the freedom the writers have with Futurama. They can create any character, any alien species, make fun of anything in the 20th century, concoct any "history" for us between now and 3000AD, and just have loads of fun.
I'm hoping this series stays alive for decades. No excuse for the overall quality to go down with age like it has with The Simpsons or any other TV series for that matter.
Oh yeah, zsouthboy, I love all episodes with Zapp, but I think he's best served as a side dish. Don't want to get sick of him.
