Ken Jennings honors Alex Trebek as he wraps 'Jeopardy!' guest hosting gig

"Thanks for your patience with a tough learning curve."

Ken Jennings closed out his six-week "Jeopardy!" hosting stint on Friday, having served as the first person to keep the show running after the death of Alex Trebek.

Before signing off one last time, Jennings took a moment to honor the beloved show host.

Jennings ended his heartfelt shoutout with a blue heart emoji.

While a new guest host will step in on Monday, Jennings will remain connected to the show as a consulting producer.

The 46-year-old trivia whiz teased the upcoming roster of famous faces who will step in for Trebek until a permanent replacement is found.

"Stay tuned for a carousel of surprise guest hosts, each more surprising than the last," teased Jennings in a follow up tweet. "Collect 'em all!"

The second guest host will be "Jeopardy!" and Wheel of Fortune executive producer Mike Richards, who will steer the ship until March 5.

Katie Couric is set to take over from March 8 through March 19, where by Dr. Mehemet Oz will pick up from there. His shows are currently listed as "TBD."

Following Oz will be Aaron Rodgers, Savannah Guthrie, Anderson Cooper, Mayim Bialik, Bill Whitaker and Dr. Sanjay Gupta.

The show previously revealed that, starting in March, each guest host will single out a charity for the show to benefit and the show will donate the cumulative winnings earned by all the contestants at the end of the host's tenure.
