Kenneth Parcell, the page from "30 Rock," made his way on to Conan's set last night. He was bringing an NBC tour group around to see the former stage of the "Tonight Show." "NBC spent more time building this studio than using it," he noted. When Conan asked him to move his tour back, Kenneth said that this was the 5 O'clock tour. Any later and it wouldn't be the 5 O'clock tour.
