I've done panel shows, which I enjoy, and on those you're recording half-an-hour of TV and sometimes they film for two hours. But with 'Britain's Got Talent,' you're on camera for eight hours, with a large theatre audience watching - and in between you're being filmed for ITV2 as you eat your lunch.

There's something about being a comedian that means you have to not be scared of failing because failing is part of the process.

I don't have a lot to share with other men. My heart sinks when I get into a taxi and someone starts talking to me about football.

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.

People think writing a children's book is something you could do in an afternoon but it's actually really hard.

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.

I can't see why anyone would want to be in politics because you get so much criticism.
