Ikea shoppers got more than they paid for when a guy donning a wig, leotard, and Christmas lights started dancing to Sia's "Chandelier." [1] It all went down as Scott Nelson's friends recorded him, and now the video, titled "Holiday Chandelier," is available on YouTube. If you thought Lena Dunham's performance of Sia's massive hit [2] on Late Night With Seth Meyers was brave, wait until you see the moves and floor rolls that got shoppers snapping away on their camera phones as Ikea employees attempted to stop him. After you watch the hilarious clip, keep the laughter going with more viral videos [3].
