Tonight's guests kind of complement each other. One believes the Earth is hollow and contains a sun, Nazis, and Vikings. The other sells a personal cooling collar that would be perfect if you were basking under the light of the sun at the center of the Earth. Now all we need is a personal margarita collar and an anti-Nazi collar... maybe they can get to work on that.
