All three “Jeopardy!” players were left stumped by a final puzzle about the hit ’80s show “Cheers.”

During Tuesday night’s “Final Jeopardy!” round, fans called the clue a “triple stumper” after each contestant failed to answer correctly.

Game show host and former “Jeopardy!” champion Ken Jennings announced the category was “Classic TV Shows.”

The prompt read, “Posted over the door of this show’s setting was a notice reading, ‘Maximum Room Capacity 75 Persons.’”

Player Lily St. Laurent, from Bakersfield, California, answered, “What is a TV show I don’t know.”

David DeBacker from Ypsilanti, Michigan, wrote, “What is MASH.”

“That’s a good guess, but that is not it,” Jennings said. 

Alex DeFrank from Brooklyn, New York, also answered, “M*A*S*H.”

Jennings pointed out, “I’m very alarmed to learn that the ’80s shows of my childhood are now classic TV — What is ‘Cheers.’ The bar in ‘Cheers.’”

DeFrank wagered $6,001, which left him with $19,199 and the title of three-day champion.

His winnings totaled $75,600. Fans were quick to share their outrage on social media and called the “Final Jeopardy!” clue “obvious.”

“Flabbergasted that FJ was a triple stumper,” one comment read on Reddit.

Another viewer wrote, “Never seen an episode in my life and I got it instantly then thought it was too obvious.”

An enthusiastic supporter joined the conversation and remarked, “During the early 1980s, both MAS*H and Cheers were being broadcast… I believe both would fit the criteria.” The individual went on to say, “This particular question stumped us both right away, my wife and I. Although we haven’t watched many episodes, a sign like that capacity one indicated it had to be a public location, and everyone knows Cheers is set in a bar.”

The popular game show has been notorious for challenging its players with pop culture questions.

Earlier this year, a “Jeopardy!” contestant walked off the stage after he missed a clue about Céline Dion.

“Sharing its title with an earlier, more upbeat Huey Lewis hit, it was No. 1 for Céline Dion in 1994,” Jennings read the clue at the time.

During a game show, Drew Goins, a participant and avid follower of the talented singer, found himself at a loss for words, furrowing his brow in deep thought but failing to provide a response.

“Drew, you’re in trouble with her now,” humorously remarked Jennings as Goins set his buzzer down, exited the stage to the amusement of the audience, and then returned to receive a warm hug from another contender.

Jennings then revealed that the answer was “The Power of Love” after none of the other contestants got it either.

“Jeopardy” shared the moment on social media and wrote, “Here’s hoping Drew’s heart will go on,” referencing Dion’s Oscar-winning ballad from “Titanic.”
