Ken Jennings knows trivia. He's the most winning champion in the history of TV's gameshow "Jeopardy." For two years, he was at the mast of Geography, European Capitals, and The Daily Double — all in all seventy-five games before he stumbled with $2.5 million in winnings.

He's been called the Michael Jordan of trivia, the Seabiscuit of geekdom. Now, Ken Jennings is turning around to look at trivia itself — why it captivates, and how it lures us in at the kitchen table.

It is the most democratic pastime, Jenning says. And by the way — what marsupial has fingerprints indistinguishable from humans?
