Slashdot Gameshow Experiences?

Rev Wally asks: "Next Tuesday, I hope to achieve one of my life long goals, as I've been selected to try out for Jeopardy! in Boston. I am looking for any words of wisdom from any one else who has appeared on/tried out for any game shows. Also, from any one at all, I am looking for you to throw random trivia questions my way, to try to sharpen my skills. Any help will be much appreciated, And I will try to keep any updates in my journal."
