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 used to have a silk dressing gown an uncle bought in Japan and when I came downstairs in it, my dad used to call me Davinia. There was never embarrassment about that kind of thing. My sister used to dress me up a lot. She thought I was a little doll.

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.

There's a sort of magic and music to comedy. Some words, some numbers even, are funnier than others. A Caramac bar, for instance, is funnier than a Milky Way.

It's important when you're married not to forget those things you used to do when you were trying to get her to marry you. You can't send flowers and buy gifts then, when you're married, say, 'Right, get my tea on'. That doesn't go down well. So you've got to keep that level of interest going.

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 haven't put much effort into my personal life and blithely believe it will turn out all right in the end.
