Improv Everywhere causes scenes of chaos and joy in public places. Improv Everywhere has executed over 70 missions involving thousands of undercover agents. The group is based in New York City. My friend Kristeen from Memories and Keepsakes sent me this YouTube video that I thought was really cool. Having spent 5 years in Manhattan and wandering Grand Central on more than a few occasions I can just imagine the spectacle this must have caused. Check out Improv Everywhere’s site there are alot more videos there.
