This is either big news for game show fans or much to do about nothing.

The show sent out a note this week that promises something major is going to happen on the show tomorrow (Friday) that has never happened on the show before:

"This Friday, March 16, 2007...for the first time in 23 years, Jeopardy history will be made...it was such a remarkable event we consulted a game theory expert, and he said it may never happen again!"

OK, now they have me curious, and since they mention game theory, I think I've narrowed it down to three possible events.
