Jeopardy! host Ken Jennings is on vacation in Seoul, South Korea.

The TV personality made a hilarious reference to the end of his 2004 winning streak on Jeopardy!

It’s been over two decades since Ken Jennings’ 74-game winning streak on Jeopardy! ended—and he’s still reminded of it often.

The current quiz show host is on vacation in Seoul, South Korea, where he lived as a child and attended the Seoul Foreign School. While walking around, Ken stumbled upon an H&R Block, which fans may remember was the answer to the clue that ended his run on Jeopardy!.

Ken joked about the situation on Instagram. “I cross an ocean, and still it tasks me,” Ken wrote in the caption on October 9.

Fans quickly caught on to the joke—and they shared some thoughts in the comments.

“Never forget,” one person joked. “GOT YA KEN! YOU GOT H&R BLOCKED!!!” another teased. “Ha ha can't believe I actually got this one right! Final Jeopardy is never my friend,” a different follower added.

From June 2 to November 30, 2004, Ken competed on Jeopardy! and earned $2.52 million over 74 episodes. In his final round, he guessed incorrectly on the clue: "Most of this firm’s 70,000 seasonal white-collar employees work only four months a year."

Ken answered, “What Is FedEx?” and bet $5,601 of the $14,400 he’d earned. Competitor Nancy Zerg guessed correctly with “What is H&R Block?” and bet $4,401, adding to her $10,000 overall earnings and putting her $1 ahead of Ken.

Considering Ken’s journey since then, we can only hope he feels differently about H&R Block now!
