Personally, I didn't like the plot of this episode that much. I also did not like Zapp Brannigan and his jokes, they weren't as funny as they were in Love's Labours Lost in Space. The episode's plot seemed force, and the only truly hilarious part was the end, when Leela said, "Let's mutiny," and that was only because it had a very 'here we go again' feeling to it, which was very funny.
The famous Zapp Brannigan accidentally blows up the DOOP headquarters, and he and his assistant, Kif Kroker, are decommisioned from DOOP. They work for Planet Express, much to Leela's dismay.
