A moment or three of aesthetic pleasure, bragging at parties, but really most days it's just so much wallpaper. No, the true purpose of art is to be stolen. Then the chase begins, the drama, the mystery, the appreciation of the craft of skullduggery.
Eventually you track down the blighter who nabbed the splotchy-whatsit, buy him a beer and throw him back in the clink. That's where he'll meet his next crew, plan the next heist, and start the whole glorious affair over again.
So cheers to the cheeky beggars who grabbed the Gogh, let the fun begin!
