Its a bizzare thing considering the show is set in the year 3000, but with the technology that is apparently available at this time - anything is possible!
The twist of them oing to the Year 4000, but it ends up being LA was fantastic! Michelle (Fry's girlfriend) wasn't very nice, actually she was quite horrible to him.
Bringing Fry's past to the show has always been a good idea. My favourite episode is Jurassic Bark which focuses around Fry's dog in the year 2000. This is another goodie. My favourite scenes involved Fry and Bender scaring the people who arrived in the year 3000.
