I'm not gonna offer too much preamble to this, writer-actor-Colonial surgeon John Hodgman's address to President Obama at the 2009 Radio and TV Correspondents Dinner. I'll just say that it's a nimble, brilliant dissection of what it means to be a nerd and how the Bush administration was staffed by jocks. Oh, and how President Obama may just be the man to straddle that great cultural divide.
By the way, I know the answer to those three Dune questions Hodgman posed at the end. Without doing any research. Because I am a geek. Do you? (I'll pop the answers in the comments.)
