You know John Hodgman as the PC guy in all of those Mac commercials (or perhaps from The Daily Show). I don't know if he really uses a PC in real life (he could very well be a Mac guy), but I do know that he's a very funny man. Last night he spoke at the Radio and TV Correspondents Dinner, and gave a very clever speech about President Obama, nerds, geeks, jocks, and Star Trek. You can tell Obama genuinely enjoyed the speech.
