James K. Polk was actually an absinthe drinker who once drunkenly declared statehood for his own sideburns??

In case you don't remember, Ken Jennings is the world champion Jeopardy player, who 74 games in a row and $2.52 million on the show. So I'd guess he's probably not just making it up! And yes, his blog is a lot of fun to read.
