207 pranksters stand still for 5 mins in Grand Central Stn

In this video clip, the Improv Everywhere group brings 207 apparently normal people into Grand Central Station, whereupon they all freeze, at exactly the same instant, for five minutes, standing stock still, as though they were caught in some kind of time-loop. Around them, the Grand Central crowd looks on in wonderment, trying to figure out what's going on -- a little scared, but delighted too. When the frozen hundreds all begin to move again at the same instant, the crowd gives them a standing ovation.

We got great reactions from the folks who encountered us. Strangers started talking to each other, trying to figure out what was going on. With wireless microphones hidden in our shirts, a few agents and I struck up conversations with folks. I convinced one guy to grab a cell phone from a frozen woman's hand. He did it, laughing uncontrollably as he gently put it back in her hand. My favorite reaction was from a female cop who witnessed the whole thing from behind her NYPD recruitment booth:

Me: Do you know what that was?
Cop: I have no idea! That is the craziest shit I've ever seen in my life, AND I'M A COP!
Me: Ha. Yeah, it was weird.
Cop: You wanna sign up to be in the NYPD?
Me: No thanks.
