I heart Ken. He made Jeopardy really fun again. My wife was put on bedrest during her pregnancy and wasn't able to get out much, but Ken Jennings visited her every night via the magic of TV. I don't think he ever expected to become the multifaceted phenomenon that he is, but he meant a lot to my wife.
If you're too cynical to still like Ken after he manages to lose the Jeopardy Ultimate Tournament of Champions tonight
