From the stage I've seen people of all ages absolutely roaring at really good toilet humour.

There is a lot of rubbish written about toilet humour - people saying it is childish and pretending it is beneath them - but there is no doubting the effectiveness of a really good willy gag.

We had so much fun in Ghana and they are really lovely people.

On stage, we just want to generate hysteria. We don't care about looking cool or posing.

People expect us to be different, but we're not. We're very similar people, and it's because we're so similar and close to each other that we make each other laugh - in fact we make each other laugh more than we make anyone else laugh.

So it just wasn't in my house. Anywhere, I looked like I knew about the toilet.
