Via Pharyngula, this is a very funny story. Apparently promoters of the upcoming Simpson Movie have painted a giant Homer Simpson next to the famous artwork known as the Cerne Abbas giant. This figure is held by Wiccans to be an ancient fertility symbol, but there is no record of it before the 17th century, and many scholars feel monks from Cerne Abbas, a major Benedictine monastery, would have destroyed it if it was really a pagan image. It is more likely either a hoax or, according to an alternate interpretation, a caricature of Oliver Cromwell as Hercules.
Whatever its origins, it is now a national symbol and owned by the National Trust. It was covered during World War II to prevent the Germans using it as a navigational landmark.
For those worried, the paint is biodegradeable and will wash away when it next rains. Apparently the local 'pagans' are angry and have promised to perform some rain magic to hasten that day. Hmmm, how hard can it be to manufacture rain in Britain?
