Reminds me of an old joke about the dean of a university complaining to the head of the experimental physics department about how much his department costs. "You have all that expensive equipment," he says. "Look at your counterparts in the theoretical physics department. They're as cheap as the math department: all they ask for is pencils, paper, and erasers." He stops and thinks for a moment. "And the philosophy department is cheaper still. They don't even ask for erasers."
