"Reading Rainbow" host LeVar Burton has once again joined the chorus calling for him to guest-host "Jeopardy!" Since the tragic death of host Alex Trebek, the game show has seen a slew of special guest emcees, including Katie Couric, Mayim Bialik, Aaron Rodgers and more. For some time now, fans have been calling for Burton, 64, to be given a shot on the show.
