I think comedy is a bit more international than people credit. I happily watch lots of American shows and American comedy films. If I did a list of the top 10 comedy films in Britain, there's no sense that it would probably be different than yours.

When you are doing endurance swimming you just need to take in as many carbs as possible to put on as much weight as you can. Basically you can eat whatever you want, which can be quite fun. Everything is guilt-free.

I had a very happy childhood, but I wasn't that happy a child. I liked being alone and creating characters and voices. I think that's when your creativity is developed, when you're young. I liked the world of the imagination because it was an easy place to go to.

Children's books are often seen as the poor relation of literature. But children are just as demanding as adult readers, if not more so. I should know. I'm a children's writer myself.

I still enjoy my life, and I feel like I've achieved enough things that if I never did anything again, I'd feel confident that I'd still have made my mark in some way. But maybe the self-loathing bit is the element that makes you strive for more. Makes you strive to be better.

It can be difficult to be subtle and not cartoony in prosthetics. But when you see characters like Bubbles and Desiree from 'Little Britain' on screen, it makes all the hard work worth it. It's such fun watching those transformations.

I know some of my parents' friends think 'Little Britain' is in incredibly poor taste. But swimming the Channel? You can't really say anything negative about that, can you? There's nothing better than making your parents happy. The glee on my father's face that day was amazing.
