"They told me that I was coming on to talk about what you can and can't say in comedy about politics. But it seems to have grown into a wider thing about how Katy Perry accidentally used an islamic symbol in a music video," he explains afterwards.
"Also, I have written thousands of words on blasphemy and it's incredibly nuanced. Whenever I try and explain it on a programme like this it gets boiled down to a sentence - which if you've had five years of work wrecked by religious people and have friends who are religious you are very careful to maintain a nuanced position."
"The idea that you could discuss blasphemy and offence as an adjunct to something else... well for a start you'd have to talk about how the whole world is different post-7/7. Most of the time I just won't say anything about it."
