I buy smoked mackerel in a vain attempt at being healthy. I do actually really like it, and you don't have to cook it, which is handy.

I pay a bit more than lip-service to health: I don't eat chips or pre-prepared food, and it might be a comedy sacrilege to admit I do like vegetables, fruit and salad and stuff.

I'm just trying to spread the word and upturn the myth that actually you should be resting after cancer treatment. You shouldn't; you should be getting out and doing any kind of exercise you can. You don't have to run a marathon, but you just have to up your activity levels.

I tend to think the world is a bit of a miserable place, so anyone who can add to people's optimistic, cheerful side is doing a good job, which is what I hope I'm doing.

What could be funnier than a fat person trying to run a marathon?

I think my comedy, the put-downs I do to hecklers, are the accumulated bitterness of years of people feeling that it's perfectly acceptable to make a comment on your appearance when they don't even know you.

There's lots of different feminist groups. It's not as straightforward as just looking like a plumber.
