Blue sty thinking

Monkey is a sucker for a publicity stunt to, say, launch the DVD release of a movie of a long-running TV series. So it is with some inevitability that we turn to the release of the DVD of the Simpsons Movie, which was accompanied by the appearance of the "Spider Pig" (you'll have to watch the movie) between the chimneys of Battersea power station in south-west London. Older readers will remember Pink Floyd did a similar thing with a pig (but not the spider bit) to accompany the release of their Animals album 30 years ago. Unlike the Pink Floyd animal, Spider Pig did not break free of its moorings. At least, not when we last looked.
