First ever 3-way tie on Jeopardy:

The three contestants on the venerable game show all finished with $16,000 after each answering the final question correctly in the category, "Women of the 1930s," on Friday's show.

..."We've had a lot of crazy things happen on Jeopardy! but in 23 years I've never seen anything like this before," host Alex Trebek said.

The show contacted a mathematician who calculated the odds of such a three-way tie happening -- one in 25 million.

The three contestants, Jamey Kirby of Gainesville, Fla.; Anders Martinson of Union City, Calif.; and Scott Weiss of Walkersville, Md; were all declared champions and taped a rematch that will air Monday.
