There are so many more possible shapes, I'm a bit dissatisfied with the lack of variation in the infographic

E.g. the Simpsons episode with the Monkey's Paw is a roller coaster of ups and downs

Maybe the 8th is an implied nested recursion. It's the story of Mr. Vonnegut telling the story of the other 7 shapes.

But his story has "New Testament" shape - he worked on his thesis, and then it was rejected by his fellow academics. Now, a successful author, he became vindicated by these popular articles.
