Well, I'm studying... just in case. I don't want to get the call and then think, "gee, I could have learned that stuff a year ago!"
Your son did a great job! And I was hoping for him to win too... but Jeopardy! is a real gamble. I usually do pretty well with the game but that last question is so random that I miss it about half the time.
And after having been through that in-person audition... it isn't as easy as it looks. Anyone who makes it through a couple games has a high tolerance for stress. (I had to run off to the Cheesecake Factory in the bottom of the John Hancock Building to recover!)
