In the bleeping ADS he was doing Headlines! He must know that is why some of us watch! He indeed had months to prepare. Oh well.
Jay DID do the headlines, but at the END of the show. Maybe that was something else they “changed” in order to try to make the new show look “different” than the old show. I have no idea why they would want to do that except to try to avoid stepping on Conan’s toes. But my answer is, “So what? Step on Conan’s toes.” With Jay on at 10, Conan’s ratings will take a beating anyway.
