Carlin also remarked, "Inside every cynical person, there is a disappointed idealist".
UK comedian and political activist Mark Thomas is often accused of being a cynic, because he always assumes the worst of the government and corporations. He insists that he's an idealist — he believes he can change the world for the better and is prepared to try. It's the people he goes after, who "invite evil in for a cup of tea", that are cynical.
Australian comedian Adam Hills is firmly in the idealistic side. Early in his career he decided his joke "The reason I hate Americans; is that they name their children according to virtues they want them to imitate..." worked just as well with the word "love" instead of hate, and in the end, made the whole thing a lot funnier. His act is very uplifting and positive.
