Contrary to what the comic might say, Ken Jennings is a cool guy. I read his blog; he’s quite a witty, self-deprecating guy. His recent re-appearance on Jeopardy to square-off against Watson prompted an IAmA on reddit which has some pretty amusing banter.
I still think I can take him in a fight, though. I just need to stretch first. And only if there are favourable winds. And also I get a sword.
