Fallon takes on 'Tonight': 'I can't believe I get paid to do this'

Outside Studio 6B at 30 Rockefeller Plaza, the once and future home of "The Tonight Show," the smell of fresh paint and sawdust fills the air.

Visitors to one of the last tapings of "Late Night With Jimmy Fallon" are led up a back staircase by an NBC page, winding carefully past dusty drop cloths and dumpsters piled with construction waste.

It's just a matter of days until the launch of "The Tonight Show Starring Jimmy Fallon," and if NBC's hive-like headquarters aren't quite ready, Fallon most definitely is.
