Even if it was, I have never seen it. what a great idea. I have watched several of their videos now.
I love the idea of Gorilla tactics mixed with performance art and art in general.
Way back in college, I was part of the MTA (MIME TERRORIST ASSOCIATION). We were for hire. People could put a "hit" on someone. We would be in mime garb and we would cream pie whoever the hit was on. 1 pie was funny. An army of 15 - 20 mimes pieing some poor sap was friggin hilarious. Usually the hit was done in a very public place and much planning went into it.
In later years when we saw Bill Gates get pied, we roared with laughter. It was some other kids with equally mischievous thoughts (just bigger balls). We chose mimes as several of us were clowns and hated mimes. We just decided what beter way to spread the love.
For more info about clown / mime rivalry, see the movie "Shakes the Clown".
