Totally Amazing (JM)

This is the craziest thing I have ever seen. Linked below is a video Grand Central in the middle of a work day. A troupe of over 207 people just froze in place for over a minute. I work literally next door to Grand Central and only wish I had been there when that had happened. Could you imagine what it must have been like. I suspect I would have started being terrified of some sort of alien invasion, but then I am not particularly stable. Anybody else have thoughts on how they would have reacted to this?
