Michelle is reading "Microserfs" and took up the meme in that book of defining herself by her dream Jeopardy categories. 

Cool idea - here's mine:

The Beatles
Useless Pop Culture Trivia
21st Century American Politics
Nonfiction
Potent Potables
Opera (because there's always that one category where you go, "ah, crap"...even when picking for yourself, I guess!)

Here's a good article on "how to win on Jeopardy" in case you ever make the cut.
