Overview

• On the July 30 episode of Who Wants to Be a Millionaire?, Jeopardy! host Ken Jennings surprised viewers by enlisting Matt Damon as his trivia partner and reigniting their decades-old riff with host Jimmy Kimmel.
• The contestants used the “As the Host” lifeline to nail the $500,000 Steve Martin look-alike question and then activated the 50:50 option to pinpoint Petrichor on the final million-dollar clue.
• Their correct answer triggered confetti and a $1 million donation to Damon’s nonprofit Water.org, which he said will extend clean water access to roughly 200,000 people.
• Kimmel offered a begrudging handshake onstage, playfully chiding Damon even as he acknowledged the pair’s triumph.
• With 4.24 million viewers tuning in, the episode became ABC’s highest-rated entertainment telecast this summer and the show’s best audience in over four years.
