Okay so the only way Zapp will ever get with Leela again is
A. It's only an actor that is dressed to look like Leela.
B. He keeps her weak, dehydrated and in emotional turmoil thinking they are the only two humans left in the universe (though aren't there humans on other planets besides Earth? I mean really with how far the universe is in Futurama you think there would be other people spread out throughout the galaxy)
C. It's for the fate of the human race that the two procure relations.
I guess I can buy that. I saw images of this episode and was weirded out by the concept but it does work. Though by the end it does make Zapp out to be a total inconsiderate jerk desperate for sex which... I guess fits his character actually. There should of been a better end though then just cutting to the last Brannigan file but the rest of the episode was pretty solid. They probably could of cut back on some of the Death Star refrences in the first act (since besides Zoidberg wondering who would pilot a ship into what they kept calling a Death Sphere) but everything else was pretty good. Leela volunteering and Zapp volunteering to be with her, "that better be the control stick" (yeah really between that, the nudity, "V-Giny" and the ending they really are dirting up the show's image. Then again Futurama always has had these sex jokes so I shouldn't be too surprised), Amy suggesting an orgy and later dressing as a dominatrix, The Planet Express crew trying to stop all the sinning at the "Pubic Library", Bender getting it on with the back of the satillite dish, the revelation that Leela and Zapp were on earth all along (not nearly as clever as the last episode twist), Leela beating the hell out of Zapp and Leela rushing to have sex with Zapp to stop the earth from being blown up. I also think that Death Sphere was Craig Fergauson since he was suppose to have a guest role in this ep and that would of been a good slot for one. Not as good as the last ep but still good though I hope that's the last Zapp focused ep for a few weeks at least.
