Not just art. They were making memes. Every strip has the same structure: Everett makes a statement of common decency, some random dude disagrees, then Everett physically assault the random dude. This is literally a meme template, from the early 1900s.

Question is: will the meme evolve in a similar fashion that we see modern memes evolve? Or does the fact that it has a single author prevent this natural evolution?
