We love a bit of flashmobbing here at MM (this one was particularly memorable and popular).
So when MM reader Jess found this on Oprah's website, she thought it might make a cool clip. She was right.
According to the website:
It's the flash mob that took over Chicago's Magnificent Mile. Watch 21,000 of Oprah's biggest fans perform one of the biggest dances in the world to the Black Eyed Peas' "I Gotta Feeling."
