My Favorite Martian Economist

So my favorite economist won the Nobel-ish Economics Prize. Why is Paul Krugman my favorite economist?

1. As Patrick Nielsen Hayden said, for "his distinguished work in the field of Being Right".

2. He became an economist because he wanted to be Hari Selden.

3. He knows Doctor Who.

4. He quotes Monty Python.

5. He posted a LOLcat at the New York Times.

6. He wrote a paper on The Economic Theory of Interstellar Trade.

7. He writes as though his readers aren't dumb.
