Ask HN: Who would you invite to your "fantasy dinner party" and why?

In the spirit of getting to know a bit more about fellow HN-ers and their tastes, I would like to pose the classic question:

Who would you invite to your "fantasy dinner party" and why?

Rules: 1. 5 guests only (excluding you as host) 2. guests can be living or dead 3. famous, infamous and/or "recognisable" guests are preferred (NOTE: It's YOUR fantasy so lesser known guests are accepted, but please provide a short background/description to help readers)

Can't wait to hear your suggestions :)
