GBS telling the truth

There was one interesting quotation on speaking the truth by Shaw that went something like: My way of joking is to tell the truth. It is the funniest joke in the world."
However, experience shows that people find it easier to tell lies. Perhaps I'm a lazy chap because I know that if I tell a lie it means, if it is important enough to be questioned, I will have to tell several more to cover up the first one and that is what I can't do.
