I can't relax and sink back in the couch and watch 'Jeopardy!' the way I used to.

You watch an old 'Jeopardy!' and the categories alone are very plain. 'Poetry,' or 'Movies,' or 'Physics.' If you watch it now, though, there'll be a theme board where the categories are all Hitchcock movies. Lots more jokes, lots more high-concept categories and questions.

People are using GPS systems to find millions of little hidden objects throughout the world - often as simple as a piece of Tupperware hidden in the woods. You go to a website, you get the latitude and longitude to get the specific location of a certain specific hiding space, and then you go there and see if you can find it.

Arthur Jay Klinghoffer, a professor of political science at Rutgers University, has argued that geography seems less relevant than ever in a world where nonstate actors -- malleable entities like ethnicities, for example -- are as powerful and important as the ones with governments and borders. Where on a map can you point to al-Qaeda? Or Google, or Wal-Mart? Everywhere and nowhere.

I always bring my kids vacation souvenirs printed in Comic Sans, so they know I love them but not unconditionally.

I threw the opening pitch at a Blue Jays game, and after the pitch, the mascot asked me if I wanted him to sign the game ball, which I thought was funny. What would he write? "Best Wishes, Some Guy in a Bird Suit"?"

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.
