'Jeopardy' Guest Host Ken Jennings Chokes Up During Alex Trebek Tribute

Ken Jennings looked like a natural guest hosting the first 'Jeopardy' episode since Alex Trebek's untimely death.

The Jeopardy GOAT opened the show with a touching tribute to the legendary game show host, and almost teared up. You could tell he was choked up and emotional when talking about Alex.
