This week's concept was actually last week's runner-up in the sketchbook. While it would have been timelier right on the heels of the Congressional hearings, our insatiable oil addiction isn't going anywhere soon. It's also an underlying cause for so many of our problems, from our entanglements in the Middle East to global warming. So I went ahead with "The Hunger." It's not the most sophisticated metaphor, but I also wanted a simple, striking visual after last week's text-heavy toon.
