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.

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.

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

Performers like Tommy Cooper, who are always getting things wrong, are much more endearing than comedians who are sassy and smart.

A lot of people are obsessed with looking cool. They feel they have to look after their image.

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