Flash mob in LIBRARY

I came across this video on Break.com, and i thought it was necessary that i post it. Before this class, i never knew what a flash mob even was. After hearing the examples in class, i began to get a better understanding of the concept. I find them to be rather entertaining if done in the right way. This video that i found i feel does that, and goes beyond making a point.
Keep in mind that whats happening in this video, is all done within a School Library. Picture something like this happening in Scott Library @ york :)
