During the whole 'Jeopardy' experience, I felt like I was living a bit of a double life, I would be secretly flying out to L.A. to tape new shows, hoping that none of my coworkers would notice the absence and figure out what was going on. 'Jeopardy' tries very hard to keep their secrets.

Eratosthenes, the mapmaker who was the first man to accurately measure the size of the Earth, was a librarian.

Knowing lots of answers but being a millisecond slow on the buzzer is indeed very frustrating.

I have always loved maps.

I remember one of my last shows, the Final Jeopardy! clue was something like 'These two boys' names are top 10 boys' names in the U.S., they both end with the same letter, and they're both names of Jesus' apostles.' Now, obviously that's not a knowable fact.

As Jeopardy devotees know, if you're trying to win on the show, the buzzer is all. On any given night, nearly all the contestants know nearly all the answers, so it's just a matter of who masters buzzer rhythm the best.

I have condemned my kids to a lifetime of geographic illiteracy.
