Friday afternoons on GSN, you can win big cash prizes if you can beat Ken at his own game:
Stump the Master with Ken Jennings! Submit your trivia questions
here, and if your question is chosen and stumps Ken, you'll win $1,000 or more. Watch for
Stump the Master around 2:30 Pacific, 5:30 Eastern. That's during a break in
Chain Reaction, currently.
