For a comedian to host a chat show can be difficult but in this modern age there are lots of scriptwriters involved in any comedy project.
So, to be fair, you cannot just say Frank Skinner is unfunny, it can be the fault of the material, not just him.
I can speak from experience, I went to see a recording of that awful Anne Robinson "what's the story with..."
I had seen it on TV and thought "it can't be that bad"
Well, the jokes were awful, Anne Robinson and Marcus Brigstocke were awful and the questions were moronic.
At least Frank Skinner is funny and asks probing questions.
But good point, he does not do any stand-up but what about those world cup podcasts? were they funny ?
He's OK.
