Space Dandy - Episode 4
The space zombie story to end them all. Ironically, I think at this point, the show would be breaking a rule of its own if it began a continuing storyline, and I'm okay with that. The show's final episode could be the entire cast dying and it wouldn't even be sad because in the next non-existent episode they'd be alive again. I'm pretty sure this is why the whole space-time continuum line pulling deal was demonstrated in the very first episode.
This show fills the void that Duck Dodgers left in me.
