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

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

Most modern comedy is crap.

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.

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

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.

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