'Jeopardy!' host Ken Jennings called Dr. Amy Hummel 'the Big Kahuna' after her fourth straight win

At the end of "Jeopardy!" Monday, host Ken Jennings called Amy Hummel "the Big Kahuna." Why? Because the Milwaukee ER doctor won the game for a fourth time.

While opponent Ferdinand Percentie, a day trader from Altamonte Springs, Florida, had a significant lead going into Final "Jeopardy!," Hummel still managed to pull out the win.

Hummel's four-day winnings total is now at $85,794.

After Monday's Double "Jeopardy!" round, Hummel was at 20 correct answers and five incorrect for the game, according to The Jeopardy! Fan website.

Going into Final "Jeopardy!," Hummel was in second place with $13,800. Percentie was leading with $21,600. And, Kirsten Lundquist, a product marketer from Burlington, Vermont, had $800, according to a clip the show shared on YouTube.

The Final "Jeopardy!" clue was: "Surf legend Duke Kahanamoku has been called by this two-word nickname that describes any dominant person or expert."

The correct response: "What is the Big Kahuna?"

Both Hummel and Lundquist got it right. Hummel wagered all but a dollar, bringing her total for the game to $27,599. Lundquist wagered all she had, which meant she ended the game with $1,600.

Giving the incorrect answer of "What is Major Domo?" and wagering $7,801, Percentie's total dropped to $13,799.

"Amy Hummel comes back from second place," Jennings said on the show. "You're the Big Kahuna today."

Hummel will be the returning champion on Tuesday's episode of "Jeopardy!" The episode will air on WDJT CBS58 Milwaukee at 6 p.m. CT.

She'll be taking on Bryan Carrasco, a mortgage loan originator from Columbia, Missouri, and Laura Bligh, a webmaster from Vienna, Virginia, according to the show's website.
