The part where Leela's looking at her arm screaming, and the scream carrying on for a few seconds, had me cracking up. Also, Fry trying to tell robot!Leela from Leela!Leela. And the twist with Fry was a good one.
Great episode, and it kept me laughing throughout. I haven't seen a good part of Futurama before this, so I can't really tell if there's anything different writing-wise from its cancellation to now, but it's great so far.
