When you need something to do
Old and Busted: Flash Mobs
New Hotness: Mobile Clubbing
Mobile Clubbing further proves that white people can't dance. So much so that now we need to each have our own tune. One tune for everyone just isn't good enough anymore. It would be hysterical to see someone gently swaying to a easy-listening song and the next person pop-locking to old school 1980's rap music and the next twirling around to trance techno.
