Mission possible: "Improv Everywhere"

Slashdot turns up a flashmob-like site called Improv Everywhere. Their chosen purpose apparently is to make craziness happen (the motto is "we cause scenes"):

Improv Everywhere causes scenes of chaos and joy in public places. Created in August of 2001 by Charlie Todd, Improv Everywhere has executed over 50 missions involving hundreds of undercover agents. The group is based in New York City.

Their recent event at Best Buy was, in the words of Eartha Kitt, "brilliant, brilliant, brilliant!" And not just in overall design, but right down to the individual performances; I love the agent who brought his daughters as though it were "take your daughter to work day," which at the time was less than a week away (be sure you read/scroll down far enough to see that agent's comments about the day). And there are some wonderful tongue-in-cheek captions for the IE page documenting the event. RaptorMagic says, More power to these people, and, Check it out!
