Murray Rothbard, Karl Marx, and John Maynard Keynes
Yes, I was thinking exactly this.. hahah
I thought Keynes may be a let down though.. anyway my table seats 8.
Murray Rothbard (Natural law, anarcho-capitalism, Ethics of liberty)
Aristotle (Natural Law, Aristotelian ethics)
Ron Paul (Natural Law, natural rights)
Hans Hermann Hoppe (Natural law, argumentation ethics)
Karl Marx (Communism, International Socialism)
Adolph Hitler (Nazism, Fascism, National Socialism)
Noam Chomsky ('Intellectual', anarcho-syndicalist)
Henry Kissinger (New World Order)
I could add more... 3 was too hard

Depends what mood I am in.. eh
