I know he had cult status as part of the Mighty Boosh but I remember seeing Noel Fielding at the Apollo on Saturday night TV and he just rambled on with the most unfunny, random shit for 10 minutes.
Felt like 3 hours.
I think the audience must have been laughing out of embarrassment
I used to watch him in "Never mind the buzzcocks", and while I didn't find him funny, thought he was personable enough.
He's in the new version, hosted by Greg Davies, who I normally find very funny, but in this he's lost.
Worst of all, though, is Daisy May Cooper, from This Country. In the two episodes I watched, she seemed to spend the entire episodes pissing herself laughing uncontrollably at every inanity muttered by other contestants on the pop quiz.
