C drags me to the Chelsea galleries with some regularity. There, I am subjected to much disgusting stuff sheltered under the tolerant umbrella of Art. I don't mind this experience because I have learned that seeing garbage passed off as art can scratch your mind in a good way and help clear your vision. The object is to learn to be the first to laugh at the emperor who has no clothes. Or, to learn to appreciate a thing just because it is pretty or delicious even when it has no depth. These four clips contain some of both.
