“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.”

That’s the answer that stumped three Jeopardy contestants during the “Final Jeopardy” phase of last night’s episode. And because all three contestants wagered all of their money, the episode ended with a rare no-winner scenario.

According to J-archive.com, this is only the fourth time an episode has ended without a winner since the current version of the show began in 1984. However, for the dorkiest among you, it’s worth noting that J-archive.com does not include results from older incarnations of the show that aired in the 1960s and 1970s.

For those of you playing along at home, what was the question?

“What is Little Rock, Ark.?”

The president was Bill Clinton, and the historic event was the desegregation of Central High School.
