Okay, I admit it: I have a bit of an anarchist streak.  I get a peculiar joy out of people causing random chaos.  Rush Limbaugh’s Operation Chaos amuses the hell out of me, for example.  An Englishman who dressed up in gold lame’, wore a mask, and called himslef the Angle Grinder Man will forever be one of my favorite real-life superheros.  And, the second I learned about Flash Mobbing, I wanted to be part of one.  But there stands a group now who takes the simple flash mob and elevates it to an art form.  That group is Improv Everywhere.

This group sets up “missions” in public places in which they do some performance piece, slightly disrupting and altering the days of those who witness it.  The first of theirs I saw was the by now well-known Grand Central Station freeze:

 

And among their latest is a totally out-of-nowhere musical performed by people who had, until they started singing, seemed like normal mall workers and patrons. 

 

Sheer brilliance.
