KEN Jennings has whipped out a joke on Friday's episode that was pretty raunchy by Jeopardy! standards.

The TV host snuck in a wisecrack about the infamously NSFW final scene from Boogie Nights.

Returning winner Sharon Stone faced Jen Petro-Roy, a recently published YA author from Chelmsford, Massachusetts, and Brittany Shaw, an insurance rater who sweetly shared she has a one-eyed cat from Joliet, Illinois.

Sharon is a state children's disability manager from Round Rock, Texas - not to be confused with the famed actress - who became the new Jeopardy! champion after beating fan-favorite 2-day winner Lisa Sriken.

Speaking of showbusiness, Ken, 48, drew a huge laugh with a raunchy movie reference that may have gone over some heads.

Sharon selected the $1600 clue in Double Jeopardy under the category “Last lines of Movies.”

Ken read the clue: "Mark Wahlberg said: I'm a star. I'm a star. I'm a star I'm a star. I'm a big bright shining star. That's right."

Another contestant, Jen, got it correct as "What is: Boogie Nights."

To which Ken then snuck in: “Sorry we couldn't show the clip.”

The clue was, of course, referencing the final shot of 1997's Boogie Nights.

Marky Mark played adult film actor Dirk Diggler - and went nude for the memorable movie moment with a certain oversized prosthetic add-on.

In the closing scene, he amped himself up in front of a mirror just before he went off to perform in a pornographic film and flaunted his 'prop.'

'I COULDN'T STOP LAUGHING'

The contestants and even the audience needed a second to get it and before all nervously laughing - Jen was still chuckling while selecting the next clue.

Fans went wild in an internet Reddit thread as one user wrote: “Ken's 'Sorry we couldn't show the clip' quip about the ending of Boogie Nights is the funniest, dirtiest joke that I can recall ever seeing on the show.

I almost missed the next clue because I was laughing out loud.”

"Reminds me of the contestant who prayed for snow on her wedding day, didn't get any but "got 8 inches on my honeymoon,'" wrote another.

"A+ joke from @KenJennings after that Boogie Nights response" applauded a third on Twitter.

IMPRESSIVE 2-DAY WINNER

From there, Sharon waved around her knowledge by nabbing enough clues to have a runaway - or ensured win - by Final Jeopardy! for her second game in a row.

Sharon had $15,500, Brittany had $6,800, and Jen had $6,400.

Final Jeopardy! under "City History" read: "Over 700 years after its traditional 1252 founding date, this port city became associated with a psychological response."

Only Sharon was correct with "Stockholm" - the clue referring to Stockholm Syndrome, and she added a safe $1,100 to win $16,600 and a with a combined $33K.

Other Reddit users then expressed excitement to see how far Sharon - who revealed her sister was also once on the game show but came in third - will go.

One fan wrote: "I rooting for Sharon to be a five-day champ! So far there are no females on the leaderboard for this season."

Another agreed: "Sharon has dangerously good recall. By which I mean: it feels as if she'll get almost any question she knows the answer to if she has at least a couple of seconds to ruminate. And she knows the answer to a lot of questions."

A third person similarly expressed: "Sharon is quietly dominating with her 2 lock games and 4/4 on Daily Doubles. I’m hoping we see her in the next Tournament of Champions!"

A fourth person snarked: "Wow, this game show is desperate for a woman champion to be in this year's Tournament of Champions. That being said, yay for Sharon!"

A fifth wrote: "Two days this week with all-female contestants. Can the producers be bending over backward to get a woman Tournament of Champions-qualified? As sharp as Sharon has played so far (two lock games), they may finally get one."

There have been no female contestants to qualify for September's 2023 Tournament of Champions this entire season, it takes four wins to do so and five to lock in a position.

So now all eyes are on Sharon, who also has done impressively well on rebound clues - or picking up other contestants' incorrect responses.
