I just got to "Godfellas", the episode in which Bender drifts through space and becomes god to a race of little people who live on him.
I used to not like Futurama, but this is the episode that turned me around on the show. It was after loving this episode that I tried to watch every re-run I could. None of them could quite measure up to this episode for me, but a few came close. I realized that I'd let my annoyance with Dr. Zoidberg color my perception of the show.
And honestly, in this run, now that I'm watching from the beginning, I even like Dr. Zoidberg, which is different. I had never seen the first few episodes of the first season before, and those are pretty key in laying the foundation of the ridiculousness of Zoidberg. It doesn't change the fact that his bits are stupid, but it provides a context for their stupidness, which makes all the difference!
But yes, getting to "Godfellas" again, I just loved this episode again. Such a fresh take on the trope of playing God. I still think it's a better take despite Rick & Morty's recent episode where Rick has created a tiny universe, and on it is a scientist who has also created a tiny universe of his own.
