Alex Trebek hints he'll be done with 'Jeopardy' by 2020: Who does he want to replace him?

Alex Trebek isn't just thinking about leaving "Jeopardy": He's also thinking about his potential replacement.

"Your contract is up on 'Jeopardy' in 2020," TMZ's Harvey Levin mused to Trebek on the newest episode of Fox News' "Objectified." "Can you imagine a life without 'Jeopardy'?"

"Sure," Trebek replied, prompting Levin to ask what are the odds that he'll renew his contract.

Trebek's answer was telling: "50/50 [chance] and a little less."

The iconic game-show host has given real thought to who should take over his daily "Jeopardy" responsibilities. For him, the frontrunners are sportscaster Alex Faust and attorney Laura Coates, who "appears on some of the cable news shows from time to time."

Coates, a CNN analyst who also hosts her own Sirius XM show, was tickled, tweeting that she's "incredibly honored and humbled" that Trebek even "knows who I am," much less would like to see her to host the TV fixture.

Faust hasn't yet responded to Trebek's call-out.

Trebek also revealed during the "Objectified" interview that he does sometimes rehearse tricky phrases before going on the air. If there are words that are going to be difficult to say properly, I make diacritical marks. So that the people at home think, 'Oh gosh, Trebek is so bright.'"

"Objectified" airs on Fox News on Sundays at 8pm.
