Stephen Colbert
Stephen Colbert is a writer and actor. In his Comedy Central show, "The Colbert Report" (pronounced cole-BEAR re-POR) he pretends to be a Bush supporter and uses this stance to poke ironic fun at the Bush administration. I don't think he actually supports Bush, but is making fun of us.
He coined the word "truthiness" to refer to the quality possessed statements which, though factually false, are repeated by supporters who feel in their hearts that they ought to be true, and regard it as quibbling to object to their falsehood; Creationists, Neo-Conservatives, Bush supporters, and many others are proponents of this style of thinking.
Colbert has poked fun at Wikipedia and its apparent democratization of truth, and caused trouble for Wikipedia by suggesting that his listeners alter articles.
