You're entering dangerous land when you start theorising about comedy.

I remember once having to stop performing when I thought an elderly man a few rows back from the front was actually going to die because he was laughing so hard.

We only have one agenda, which is to make 'em laugh their pants off. Unless they are girls, of course, when it is to make them laugh their bras off so we can get a quick look.

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.

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

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

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