Say: Freeze!

New York based Improv Everywhere have already accomplished over 70 "missions" in which they are performing improvised performances with hundreds of "agents".

Before you think: "Oh, more "FlashMob", snore..." check out their "Frozen Grand Central"-Improvisation. Here they got more than 200 people "freezing" at exactly the same time for five minutes. Its a wonderfull and touching experiment.

I don´t know how much press coverage this got (and seeing that it already has over 6 million views on youtube, it was probably a lot) but this is such a wonderfully executed prank, I had to watch it several times!
