Ninja Flashmob at UC Berkeley

This happend at my school. I'm so proud of all us ninja-students. Watch!

Confused? Here is a definition of a flash mob:
"flash mob describes a large group of people who assemble suddenly in a public place, do something unusual for a brief period of time, and then quickly disperse."

I'll keep you posted when the next one happens. I'm gonna try to be in it!
