I'm going to go ahead and embarrass myself publicly on the internet and admit I have no idea who this guy is. I feel like I should, though. And hey, man, if the comics thing falls through someday, you could always eke out a living with political/pop culture caricatures.
LOL well; the whole show revolves around the theory of ancient astronaut theory; basically that every deity and every weird thing unexplained at the moment by science or history is attributed to aliens that visited earth hundreds of years ago; and this guy, who is a historian, always sounds so excited about how it 'could be' aliens, etc. The show itself is fun to watch; but this guy is hilarious sometimes; and when you watch the show; the beginning of the series he has normal hair, and then he starts looking crazier in the later shows.
