Human Mirror subway improv trick

An improv group in New York City called Improv Everywhere uses volunteers, called agents, to create dramatic scenes, called missions, in a variety of locations around the world.

Since 2001 they have created seventy missions, ranging from lining up 700 people with flash cameras on the Brooklyn Bridge to 200 people suddenly freezing for five minutes in Grand Central Station. The scene was later recreated for an episode of Law and Order SVU.

Their latest mission involved filling a subway car with eight sets of identical twins and watching people's reactions. Watch and enjoy.
