As it was based on a viewers poll, enough people must disagree with you to put him third. His stand-up show is pretty good, and that's what is being judged, not The Office or his appearance on Graham Norton.
I'm more annoyed that someone like Lenny Bruce is placed below such comic genuises as Johnny Vegas. I know why it happens, but it shows how meaningless such a list is.
The show was bad, even by clip-show standards. Too much talking head comment and not enough of the stand-ups themselves.
