Brian Williams' news magazine 'Rock Center' premieres Monday night at 10PM ET, and to celebrate the occasion, Williams gave Al Roker a tour of his new set, built conveniently a few steps away from the set of his other gig, 'NBC Nightly News.' Williams, in his after-hours slightly sardonic style, showed Roker his "conversation nook" and described what the tone of the new show will be.

As Roker sat on his couch and immediately began talking about his first career TV appearance. Williams flashed the dry sense of humor that may come to define 'Rock Center,' and asked "How much of this is gonna be about you, and how much, by percentage, will be about our new broadcast?"
