He sang the song but it was part of a bit, including the reactions. It was framed as a time-travel look into the future of the show if he actually did something like that
I remember a few of his jokes being okay/good, but a lot of it was bad and cheesy. Bill Maher would piss off half the people watching so unfortunately they wouldn't use him but I would like to see that. Kimmel seems likely, or a return to Hugh Jackman.
Holy crap at how many people disliked him in this thread. I don't care for his shows, but I thought he was a great host. I was really caught off guard and surprised.
Neil and Craig are producing again, so the first question for any new host should be, Can he/she sing? Then you ask if they can dance, THEN you ask if they can tell a joke.
