Matt Damon And Ken Jennings Risk It All On Who Wants To Be A Millionaire — But Did They Win Big?

Jimmy Kimmel's longstanding feud with Matt Damon is only going to get more insufferable from here.

Damon, alongside Jeopardy! host Ken Jennings, competed in Wednesday's primetime episode of Who Wants to Be a Millionaire, hoping to take home the $1 million grand prize for water.org, which Damon co-founded in 2009.

After a dramatic hour, it all came down to this question: "Which of these words is often used to describe one of the most beautiful auditory effects on Earth: the sound made by the leaves of trees when wind blows through them?" Their four choices were "apricity," "petrichor," "susurrus" or "eudaemonia."

With their 50/50 lifeline still in play, the duo knocked out two of the possible answers, leaving only "petrichor" and "susurrus." Since Jennings knew the definition of "petrichor," a pleasant fragrance that typically comes after a rainstorm, he deduced that the correct answer had to be "susurrus." And he was right!

"Sometimes it's better to be lucky than good, I think," Jennings said as he and Damon breathed a collective sigh of relief. "It is so awesome having Ken Jennings as your partner in a trivia game," Damon added with a laugh, prompting Jennings to ask the audience (so to speak), "Everybody but Jimmy Kimmel, do we love Matt Damon, or what?"

"You're turning this into an uprising!" Kimmel said. "I'm coming on Jeopardy! with someone you hate! Then came the moment of truth, which Kimmel described as "the least dramatic million-dollar moment in Who Wants to Be a Millionaire history."
