There is this awesome group called Improv Everywhere. They set up situations with tons of improv actors and film the resulting scene. They’ve done things such as show up to Best Buy wearing blue polo shirts (looking like Best Buy employees), going to Abercrombie and Fitch and taking off their shirts, wearing no pants on the subway, and freezing in Grand Central Station. There latest video is a spontaneous musical in a food court. I love the people’s reactions. They are an impressive group and I love their videos. Here is the musical.
