It's almost as if the comic wasn't real and that the entire video was commenting on the world of Political Cartoons!

There are literally about a half dozen professional newspaper political cartoonists left in the world. They actually meet once a year and decide who drew the best political cartoon that year. Also, woe betide to anybody who attempts to draw political cartoons outside of their approval. It's a weird, self-recursive little subculture.
