My appreciation of this episode is definitely enhanced by the fact that I used to work for the Chase Bank (if you've seen the episode, you already know what I mean -- if you haven't, well, you'll still enjoy the moment when you see it.)
Any show that can get Vice-President Al Gore to appear as himself can't be bad, eh? Other voice "appearances" by Stephen Hawking, Nichelle Nichols, Gary Gygax make this one of the more intriguing episodes to watch again.
Okay, so it's not the biggest part for Zoidberg, but it is one of the funniest. Look out for Leela's lunch, too. Awwwww.
Only drawback I see is with the wrap-up -- I could have done without that "this was all a dream" kind of ending.
