I've now got a 35,000-word document of quotes from people who hate me, a lot from the 'Guardian' comment threads. Mostly, I've managed to get myself into the mindset where the criticism is quite affirming.
I read in the 'Daily Mail' that I'm one of these 'foul-mouthed comedians.' But I'm much cleaner than the people they like. Nothing gives me greater pleasure than to think that a 70-year-old - particularly someone like Alan Bennett - would like it, because they've seen a lot of stuff.
There's an assumption that my audience is all these bearded twats from Dalston. But actually, quite a lot of older people go. For them, it's like pre-alternative comedy, when there was Dave Allen or Jackie Mason or someone. Also, weirdly, because I don't really swear, they're not scared off.
I grew up in Solihull, on the edge of what was then the Birmingham conurbation. It was a good place to write comedy from. I didn't feel allegiance to anything. I didn't have working-class pride or upper-class superiority.
I think what I do is borderline art. Most people who do borderline art have to have other jobs, so I'm very grateful.
Controversy seems to be a by-product of what I do, rather like offence is the by-product of a dog urinating on the pavement. It just happens.
For other comics, it's about full-spectrum dominance, being on panel shows and having one-liners and being a good chat show guest and having a good seven minutes you can do on 'Live At The Apollo.' But I really think about these subsequent finished pieces, you know? And they don't always chop up well into one-liners and routines.
In places like Glasgow and Newcastle, audiences have a tradition of being amusingly combative. But they're not trying to ruin the act, they're trying to give you a challenge. It's like a cat playing with a mouse - the cat doesn't want the mouse to die, it wants to keep it alive for its own amusement and to be entertained by its struggle.
I don't know where the ideas come from, and it's terrifying. They seem to be absolute flukes. When I was in my 20s, I'd walk around with a notebook all the time and make sure I wrote down anything that occurred to me. Now I'm just hoping that some sort of event will descend on me.
It's interesting to me that apparently distasteful comments from the Right against weak targets tend to draw a lot less media fire than apparently distasteful comments from the Left against hard targets. That's one of the threads that runs through the show and that people hopefully pick up on.
I wasn't the classic comedy type; I wasn't bullied or extrovert. I was more the ambitious literary one who wanted to write clever little plays.
I am not comparing myself to great artists, but when you see conceptual artists at work, on some level it's reassuring to know they can paint figuratively. Likewise, when you listen to the '50s jazz people who do these vast solos, you buy into it more if they open by playing a tune.
When I did 'Jerry Springer: The Opera,' there was a big fuss, largely centered around the misrepresentation of its content. Had Twitter existed then, that would have been over in a week because people who had actually seen it would have been able to get control of the story through social media.
Personally, I don't have a Twitter account. I like to be in control of the way the stand up of Stewart Lee is perceived, I don't want to have to engage with individual people. Also, when I do look at it, loads of factually inaccurate things about me are written.
The only reason I look back is to check if I've been doing something wrong. I look at things from even three years ago and think, 'I wouldn't do that now.' Your life changes.
I'm in this for the long haul, I want to be doing this until I die. I am a standup comedian. I know a lot of people say I'm not, but I am.
You get annoyed about things in real life, and then the tragic thing is that while you are moaning on the awful injustice and suffering of something, something grimly comic will then strike you about it, like a parasite feeding off the misery of the world.
When I started on the London circuit in 1989, nationwide there were about 150 to 200 people that were what you could call alternative comedians - that weren't club comics. Now, last year when the Laughing Horse chain of clubs held a new acts competition, a thousand people entered. So, there are 800 people more.
I don't mind causing offence when I intend to, but I don't like causing it accidentally.
The idea of what's acceptable and what's shocking, that's where I investigate. I mean, you can't be on 'Top Gear,' where your only argument is that it's all just a joke and anyone who takes offence is an example of political correctness gone mad, and then not accept the counterbalance to that.
