Okay here is the structure of my podcast "The Psychology of Humour in Advertisements". I started with a straight line that introduces the topic. It's a pretty straight forward introduction and then it dips into a small story/anecdote (and that's the beginning of the trough there) and then I end the story with an explanation and a sort of definition-type part (this is the exclamation point). The rest of the podcast continues this way with examples (being the continuation of the trough) and then explanations and definitions (being the exclamation points). It ends back on the straight line, although it isn't returning to the main story. I may revise that because it may be a good way to end it off. But the straight line represents the conclusion: straight forward and kind of a summary of everything that has been said. 

It's obvious that it strays a bit from the images provided here. However, I have done a pretty close emulation to the Under the Influence episode "The Psychology of Pricing". I thought it'd be fitting for it's a similar topic so I thought the structure would work to get the idea across to listeners. Terry O'Reily opens with a brief introduction followed by a short story and then definitions with simple examples that are understandable. Finally, he ends up with a bit of a summary. I think that even if I did a different structure, as long as the message was clear, it would be okay. 

I counted 24 citations in episode 102 "Icon for Access" of 99% Invisible. I guess we'll see how close I am!
