So I'm going to talk a bit about skepticism in comics. I have two online comics in particular which cater somewhat to the intellectual crowd and also have a fairly skeptical outlook.
The first will be Saturday Morning Breakfast Cereal. It's been running since 2002 and for the most part its writer, Zach Werner, uses juxtaposition and irony to generate absurdist humor. Sometimes, though, he comes out with gems like these...
The artwork is simple but it effectively conveys his messages. The expressions, postures and gestures of his simplified characters are familiar and are easily recognized. In general, the artist puts familiar ideas into unusual context. The juxtaposition tends to result in a humorously absurd situation, but it also very effectively dismisses the argument being parodied.
Sure it's a straw man, but it's funny.
