On Friday, Ken Jennings ended his six-week guest hosting gig on “Jeopardy!,” and he signed off by giving a touching thank you to the late great Alex Trebek.

“That’s a wrap on my six weeks of @Jeopardy guest hosting. Thanks for watching, thanks for your patience with a tough learning curve…and, as always, thank you Alex,” Jennings wrote on Twitter. He concluded by reminding fans to be ready for more guest hosts on the show.

Jennings kicked off his guest hosting gig last month by paying tribute to Trebek, who died back in November at the age of 80 following a battle with pancreatic cancer.

“Welcome to ‘Jeopardy!’ Sharing this stage with Alex Trebek was one of the greatest honors of my life,” Jennings said at the time, according to Entertainment Tonight. “Not many things in life are perfect, but Alex did this job pretty much perfectly for more than 36 years, and it was even better up close.”

“We were dazzled by his intelligence, his charm, his grace, really, there’s no other word for it,” he added. “Like all Jeopardy! fans, I miss Alex very much, and I thank him for everything he did for all of us. Let’s be totally clear: No one will ever replace the great Alex Trebek. But we can honor him by playing the game he loved.”

Last month, Jennings admitted that hosting “Jeopardy!” is “nerve-racking,” and to say that he wishes Trebek was still here.

“I’m like everybody else, I wish it was still Alex out there. But the main thing I noticed is what an amazing job he did, he made it always look so effortless and graceful,” Jennings told the Seattle Refined.

“It’s been really rough missing him and also just missing ‘Jeopardy!’ with him,” Jennings added. “I think that’s what we’re grieving, the fact that he would be part of our lives, that we could have Alex hosting ‘Jeopardy!’ every evening. I kind of wanted to open the show that way and just say, ‘Look, you can’t replace a great like Alex Trebek. We want ‘Jeopardy!’ to continue. It won’t be the same, but it will still be ‘Jeopardy!'”
