Despite that, existentialcomics really is one of the funniest comics on the web today. Follow it. Seriously.
I love the comparison to "hacking" in movies! But I think in all fairness, the caricature of the thinkers here is different. TV "hacking" doesn't look anything like hacking, because the audiences don't usually know what hacking looks like anyway.
But here, the caricatures look (and talk) quite a bit like the thinkers they represent, at least in the broad strokes. Rawls probably wouldn't reason this way while settling a bill, but he does (sorta) reason this way in his writing, hence why the comic is supposed to be funny at least to those somewhat familiar with the writing.
I'm just arguing that the humor rests more on my familiarity with the topic than with anything genuinely funny about the situation, characters, or reactions. In other words, it's designed to flatter me for knowing things.
