I'm the cartoonist who created the original cartoon. My first reaction, upon seeing this post, was "Oh, cool! I've made Neatorama!"

So far, these are the only three that exist, but I'd encourage anyone else who wants to, to go ahead and remix my cartoon. The more the merrier.

And Edward, since you asked: You can buy a poster to my version of the cartoon by following the link here (also available on a tshirt). I think Bob Hayes, who made the one making fun of progressives, is planning something similar but hasn't gotten around to it yet.
