"you technically correct, the best kind of correct" is code for "shoot the bad example who only repeats 'you technically correct, the best kind of correct' and hope for the best"
Leela is right about Zapp being the worst captain. Sadly, professor farnsworth is too stupid to see how horrible Zapp Brannigan is. If Zapp gets fired again, professor farnsworth would hire him again which Leela had no choice, but to make sure Zapp doesn't get fired. In short, the reason Zapp keeps getting away with his antics because people are too stupid. I get it, the show is meant to be a comedy.
Zapp is a good example of a player who thinks of himself and not his teammates. He is so stupid, he tried to seduce Leela and failed so many times, he dragged Kiff down a lot of times, also put Kiff into doing horrible tasks, being a hypocrite to other planets and becoming so selfish. Zapp is a naive hero of the universe.
Ah, comets! The icebergs of the sky. Perhaps if we jackknife from one to another at breakneck speed we just might get a gravity boost... or something. Divert power from the shields! Full speed ahead!
