this episode doesn't really have any jokes, (other than the rpg parody thing). It's just a bunch of political commentary.
It's definitely possible to make politcial commentary funny*, but this just isn't
*an example I can think of is the episode of Futurama where there's a big ball of garbage coming to destroy Earth, and the solution they come up with is to create an identical ball of garbage to throw at the first one, which means humanity in the future would eventually have to deal with the same problem twice, but nobody really gives a shit because they see the short term solution as good enough.
the Futurama example would be an 'implicit ideology', because the narrative of the episode is about dealing with the garbage ball, while the ideology presented is about the problems arisng from short term solutions with long term consequences
this episode is an 'explicit ideology', because there isn't really much of a narrative, and you're only using the cartoon to present your ideology
in case you were wondering, there's also a 'neutral ideology' where the media product created carries no ideology whatsover and only exists for entertainment
