Britney Spears Goes Clubbing on Judgment Day in 'Til the World Ends'

The video for Britney Spears' new single "Til the World Ends" is basically a dance party set in a bombed-out city on the eve of some kind of apocalypse, which makes perfect sense. It makes a little less sense why only hot, model-looking people in high-end Mad Max gear have made it to see the end of world. Maybe this is a Darwinian thing -- only the foxy are strong enough to survive! Either way, this is a good, memorable video.
