I came across the Improv Everywhere website which organizes what I would call "street improv" in NYC. In their own words, "Improv Everywhere causes scenes of chaos and joy in public places". I have a real fondness for this form of guerrilla theater, and envy/admiration for what they've already accomplished. I found the court document from their No Pants Case interesting and a bit reassuring that the justice system can allow for some random acts of fun.
