Even though I haven't seen Futurama since May, I must say that the show's off to a good start so far. The episode was one of the best I've seen. I liked how the doctors were doing the autopsy on Dr. Zoidberg and how Leela and the Professor were trying to blend in 1947. It was interesting to see the characters in a historical time period.
The whole 'grandfather' thing was funny. Though I don't believe Enos was Fry's grandfather. So, I hope to see more good episodes such as this. That's my two cents.
