All of the celebrities who are guest-hosting 'Jeopardy!' this season

Jennings won 74 straight games in 2004, setting the record for the show's longest winning streak. He returned for the Greatest of All Time tournament in 2020 and won that, too. He now works on "Jeopardy!" as a segment producer.

Richards, who hosted the quiz show from February 22 to March 5, worked as the executive producer of "The Price Is Right" and "Let's Make A Deal" for almost 10 years before joining "Jeopardy!" and "Wheel of Fortune" in 2020. He has won three Daytime Emmy awards.

Couric, who hosted from March 8 to 19, said that while she wouldn't be interested in hosting "Jeopardy!" full-time if offered the job, she told Poynter in March that she enjoyed her time on the show.

"It was a lot of fun, but it was a very tough job," she said. "And I said to many of my friends who complimented me: Thank God for post-production."

Over 500 former competitors signed a petition calling for the network to remove Dr. Oz as a guest host, according to Entertainment Weekly.

"Dr. Oz stands in opposition to everything that Jeopardy! stands for," the letter read. "Jeopardy! is a show that values facts and knowledge. Throughout his nearly two decades on television he has used his authority as a doctor to push harmful ideas onto the American public, in stark contrast with his oath to first do no harm."

As Insider previously reported, Oz has shared a number of false or misleading claims in the past, including that hydroxychloroquine, the anti-malarial drug once touted by former President Donald Trump, could be effective at treating COVID-19, even though it is not.

He told The Ringer's Claire McNear that he believes he could manage the job while still playing football.

"I don't think I'd need to give up football to do it," Rodgers said. "They film 46 days a year. I worked 178 this year in Green Bay ... I feel like I could fit 46 into that 178 and make it work. It would be a dream job for sure, and I'm not shy at all about saying I want the job. That's how I went into it. I want an opportunity to be in the mix."

Cooper shared a photo on Instagram of his son Wyatt watching him on "Jeopardy!" and calling the hosting gig "a dream come true."

Whitaker has been a correspondent at "60 Minutes" since 2014.

Cohen won $164,603 over nine games in 2016 and won the Tournament of Champions in 2017. Alex Trebek nicknamed him "Mr. Personality."

Bialik may have one of her kids (and TikTok) to partially thank for the gig.

"My 15-year-old heard on the TikTok universe that people were saying, 'That girl from "Big Bang Theory" should do it,'" Bialik told Insider while promoting a partnership with Neuriva when asked how her guest-hosting duties came about on the game show.

She continued: "I don't know if it was my 15-year old and having to email my agent that did it or if it was something that was already in the works, but I'm super excited and honored, especially as a woman and as a woman in science to be able to present in this way in 10 snazzy blazers."

Guthrie has won two Daytime Emmys for her work on "Today" and hosting the Macy's Thanksgiving Day Parade.

Gupta serves as CNN's chief medical correspondent and an associate professor of neurosurgery at Emory University.

"I used to watch @Jeopardy with my parents and now with my own kids," Gupta wrote on Twitter. "The thing is: there is just something so beautiful and reassuring about facts, simple straightforward facts. I cherish that. An honor to be an upcoming guest host, but seriously miss the great Alex Trebek."

Stephanopoulos has been with "Good Morning America" since 2007.

Roberts will be the first Black woman to host "Jeopardy!"

Burton, known for playing engineer Geordi La Forge on "Star Trek: the Next Generation," also hosted 21 seasons of the educational children's show "Reading Rainbow."

"THANK YOU... to all y'all for your passionate support!" Burton tweeted. "I am overjoyed, excited, and eager to be guest-hosting Jeopardy!, and will do my utmost best to live up to your faith you in me. YOU MADE A DIFFERENCE! Go ahead and take my word for it, this time."

Faber is the co-host of CNBC's "Squawk on the Street."

Buck is known for his coverage of the NFL and MLB, and he has served as the play-by-play announcer for the World Series for the past 20 years.
