Jeopardy! Previews Ken Jennings' Tearful Guest Host Debut

Last week we bid farewell to Alex Trebek as his final episode of Jeopardy! was broadcast.

Today we'lll see the first in a series of guest hosts, as Jeopardy! ponders who will be named his successor. And who better to kick things off than the show's official GOAT, Ken Jennings, who tears up as he pays tribute to Trebek in his opening remarks in the preview clip above.
