Above him shone the light, large, clinical and fierce. No furniture, just whitewashed walls, quite close all around, and the gray steel door, a smart charcoal gray, the color you see on clever London houses. There was nothing else. Nothing at all. Nothing to think about, just the savage pain.

Now that I think of it Kierkegaard, Nietzsche, and Schopenhauer are pretty much the only humorous philosophers in the Western philosophical canon. Kierkegaard is a pretty funny guy; though not in a Jay Leno type of way, his is a more subtle Dennis Miller style. Nietzsche has funny lines too, though I can't imagine filling up an entire book with Nietzsche humor though. And Schopenhauer has very morbid sense of humor.

—Don DeLillo, Cosmopolis, 2003.
