Okay, I'm not a big fan of either Oprah Winfrey or the Black Eyed Peas. Having said that, this is one of the coolest videos ever. For Oprah's 24th season opener, she had her show on the streets of Chicago. Without her knowledge 20,000 fans participated in the biggest choreographed dance ever (bigger than Ferris Bueller's parade, even.) It's not clear what's going on at first, since the crowd is staying pretty still. Watch for the girl in the blue shirt -- that's when the excitement starts. Oprah is shocked (worth watching the video for that alone.) At the end of this video they explain how they made it happen.
