Conan O'Brien, still struggling to fill out a nightly talk show without his striking writers, came upon a cunning, time-wasting plan last night: forcing his guests to make it through a maze before sitting down with him. The first guest subjected to the cardboard labyrinth was venerated newsman Tom Brokaw. Brokaw was game, as you can see in the attached clip. SAG-affiliated actors across the entertainment industry are presumably thrilled the picket lines give them a better excuse to turn down Late Night than "I'm barely coordinated enough to intro a clip, let alone make it through a rat maze."
