Grand Central stunt
Great improvisation. These people <link> are very clever and this is a great stunt.
“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. ”
Maybe next time one person could go in and freeze and then another and then another like it was a disease spreading across the station.
