'Jeopardy!' releases first teaser with Ken Jennings as host

Ken Jennings' hosts first 'Jeopardy!' after Alex Trebek's death

Ken Jennings to host first Jeopardy!' episode on Monday

Ken Jennings is expected to to host Jeopardy! for the first time Monday evening.

Fans anxious what "Jeopardy!" would look like without its patriarch need not despair over Jennings' performance. Following the death of longtime host Alex Trebek, whose final episode aired January 8, the show will begin introducing a series of guest hosts until a permanent replacement is named. "Like all Jeopardy! fans, I miss Alex... very much". It included some great clips from his years as host of "Jeopardy!", including a hilarious segment showing him in various costumes - a clown, the Statue of Liberty, and Gene Simmons from KISS.

Boasting an impressive 8,200 shows 37 seasons, Trebek is the Guinness World Record holder for hosting the most episodes of a single game show. After the last one, he walks off the set. He read thousands of clues to the contestants (61 per day), but viewers and contestants could never mistake his tone for one of boredom.

As a host, Jennings has studied at the altar of Trebek and clearly tried to make as few waves as possible. The clues are the same, the "Daily Doubles" are still hidden and "Final Jeopardy" is as hard as ever.

'But there are tens of millions of people who love this show; we love this show, Alex loved the show.

Jennings, who holds the record for the longest "Jeopardy!" winning streak, opened the show with a monologue dedicated to Trebek - almost choking up in the process.

Former "Today" show host Katie Couric will reportedly also serve as a guest host of "Jeopardy!".

"Honestly, I'm with the audience", the 46-year-old said in a promo released before the show.

'It's a very demanding job, and he was just the best, ' said Jennings, who beat James Holzhauer and Brad Rutter on JEOPARDY!
