The feature has been around for a while but checkout the trivia game/widget on Yahoo's Kings page (right hand side below the team schedule). Some of the questions are completely worthless (like where was Greg Ostertag born?) and some are out of date (references to "current" Kings that now play in Toronto) but if you're bored challenge yourself to 100 questions. I didn't blow the doors off but I think my score was respectable.
I would be very impressed by anyone with a legit score in the 90% range.
