MILWAUKEE (CBS 58) -- From the podium to the lectern, the greatest of all time is ready to take over a new role.

Ken Jennings will guest host "Jeopardy!" starting Monday night, Jan. 11.

Jennings is filling in after the death of long-time host Alex Trebek.

"The main thing I learned was what an impressive, perfect job Alex Trebek did behind for 36, 37 years," Jennings said. "And I thought I knew from over there, I thought I had studied the man and understood just what a remarkable job he was doing."

Jennings says his best advice to the contestants is watch the show as much as possible.

"Jeopardy!" airs weeknights at 6 p.m. on CBS 58.
