This is just the MOST fun site ever! Improv Everywhere causes scenes of chaos and joy in public places. Created in August of 2001 by Charlie Todd, Improv Everywhere has executed over 70 missions involving thousands of undercover agents. The group is based in New York City. Feels like being in school again, except the pranks are so sophisticated. I may just have to become an agent if I’m in NY during one of their pranks. Here’s a fun one: On a cold Saturday in New York City, the world’s largest train station came to a sudden halt. Over 200 Improv Everywhere Agents froze in place at the exact same second for five minutes in the Main Concourse of Grand Central Station. Over 500,000 people rush through Grand Central every day, but today, things slowed down just a bit as commuters and tourists alike stopped to notice what was happening around them. Look at how creative their poses are, and how NO ONE MOVES!!!
