Again, if it counts for anything:
Played for Jenks HS (Okla) 1990-92 (took second in state both school years, went to Questions Unlimited national tourney 1991), was a phone-in contestant on a 7/29/1999 rerun of Inquizition and won $250.
As for the other people I mentioned, Matt Kane played for Tulsa Memorial (again, I don't remember his J! results, but maybe someone else will), and Matt Bruce played for Tulsa Washington (and, I believe, for Harvard).
