"Ours is a useful trade. With all its lightness and frivolity it has one serious purpose, one aim, one specialty, and it is constant to it -- the deriding of shams, the exposure of pretentious falsities, the laughing of stupid superstitions out of existence . . . Whoso is by instinct engaged in this sort of warfare is the natural enemy of royalties, nobilities, privileges and all kindred swindles, and the natural friend of human rights and human liberties." Mark Twain
