Giant Inflatable Spider Pig

Is it a bird? is it a plane? No - it's a giant inflatable Spider Pig.

The cartoon balloon rose above London's iconic Battersea Power Station to mark the release of The Simpsons Movie on DVD.

The stunt was a cheeky recreation of Pink Floyd's Animals album cover shoot in 1977 - when their pig broke loose, shot up into Heathrow's flight path and startled pilots at 40,000ft.

This time, to make sure history did not repeat itself, an SAS trained marksman was on standby to take Spiderpig down if he looked like flying off.

Jon Stewart, the host of Comedy Central's The Daily Show, will be making a guest appearance as himself on the January 6, 2008 episode of The Simpsons, along with Dan Rather.

"It's truly a great honor and I'm very excited about it," said Stewart.

Synopsis:

After Springfield becomes the first city in the nation to hold a presidential primary election, excitement builds as reporters from around the country, including Jon Stewart and Dan Rather, descend upon Springfield to cover the debates. When the candidates turn out to be less than compelling, Kent Brockman announces an unexpected turn of events: Springfield voters rejected all of the candidates and embraced a write-in: notorious bed-wetter Ralph Wiggum.

With Ralph as the new presidential front-runner, Republican and Democratic party leaders fight to win him over as their candidate. Find out if Ralph can make the leap from Sesame Street to Pennsylvania Avenue.
