Looking back, we couldn’t have kept the Flash Mob from meeting the Thriller Wedding Dancers and going global if we tried. On Saturday, the world will experience the love child of these two wacky pop-culture trends when thousands of Michael Jackson fans clench their hands into claws and swing them from side to side in an attempt to break the Guinness World Record for “Largest Simultaneous ‘Thriller’ Dance”. The event—which has almost as many sponsors as expected dancers—will be hosted in Los Angeles at LA Live, where trained dance instructors will hold rehearsals from 1 to 5:30 (world record time!) You can stop by to catch all those shuffling feet, but you’ve got to register to participate. Thousands of people around the world dancing to Michael Jackson’s “Thriller” at the same time? There’s got to be a symbol for 2009 in there somewhere.
