Great metaphor about the role of storytelling by social media strategist Dave Delaney, in an interview by Presentation Revolution:

6. You have given your fair share of presentations. How important is story as it relates to the world of presentations?
The story is the bun. The content is the meat (or vegetarian patty if you prefer). The bun holds it all together, it makes it enjoyable. Without the bun you have a mess in your lap. Have you tried eating a burger without a bun, it’s very messy, I don’t recommend it.
