my favourite segment in this episode was the first one where the simpsons kill flanders...or do they? homer starting to tell flanders where to hide from flanders before realising it was him was great aswell as the other hiding places he picked out. this is the funniest segment in the episode closely followed by life's a glitch...then you die.
in this segment i found it hilarious that they wasted a rocket by sending it to the sun when they could have brought even more important people to the moon and left rosie o'donnell, etc. on earth to die.
i also liked the xena ripoff but not nearly as much as the first and last segments. overall, a very well written installment.
