Mark Twain tells us, "A discriminating irreverence is the protector of human liberty." Drawn not from the warrior's quiver, Twain's irreverence is drawn from the artist's pallet. "Laughter, without a thread of philosophy woven into it, is but a sneeze at humor, genuine humor is replete with wisdom. And if a piece of humor is to last, it must do two things, it must preach and it must teach. If done effectively, that piece of humor will last forever, which is thirty years."
