Final 'Jeopardy!' clue stumps all 3 contestants, who all bet everything

NEWYou can now listen to Fox News articles!

No one walked away a winner on last night's episode of "Jeopardy!"

Three contestants failed to answer the "Final Jeopardy" clue.

The clue that stumped the three contestants was "A 1957 event led to the creation of a national historic site in this city, signed into law by a president whose library is now there too."

The correct answer was Little Rock, Ark. But the contestants, who bet a combined $33,600, all walked away empty-handed.

“We have no returning champion. We will introduce three new players,” Alex Trebek said. “So, sorry folks!”

Claudia Corriere, one of the losing contestants was a returning "Jeopardy!" champion after winning two shows in a row on Dec. 17 and Dec. 18 in 2015. She lost it all after guessing the city was Austin, Texas.

This is the first time all three contestants lost since a Feb. 7 2013 teen tournament episode.
