Watch: Massive "Single Ladies" Flash Mob Takes Over S.F.'s Main Library
We kinda wonder about the spontaneity of this flash mob, given the outfits and synchronization and the rather practiced dancing, but! We're in no mood to spoil this party with reality. Here, showing all of San Francisco's rainbow diversity, is a vast flash mob shaking its thing to "Single Ladies" in the lobby of San Francisco Public Library. Why? Because it's Friday, because it's holiday time, and because you're probably sick of "Drunk in Love" already. You're welcome.
