Is this even up for debate? Gintama is the king of parody. Heck, it makes fun of literally anything, including the creator, production team and even the show itself. I’ve only seen episodes here and there because I haven’t got the time to sit down and watch all 300+ episodes, but I guess that’s part of the charm. Since there are so many episodes and they don’t particularly rely on you watching them in order (apart from the really dark and serious arcs) it’s that one show I know I can always watch a few episodes of and be guaranteed a lot more than just a couple laughs.
