Improv Everywhere is an unorthodox comedy group based in New York City, formed in 2001 by Charlie Todd. Its slogan is "We Cause Scenes," which the group lives up to by executing non-demeaning pranks in public places. Improv Everywhere has organized and carried out over 70 missions, from synchronized swimming in a park fountain to repeating a short sequence of events in a Starbucks café every five minutes for an hour to flooding a Best Buy store with members dressed exactly like the staff, to deploying 111 shirtless male shoppers at an Abecrombie and Fitch store and more. This video features IE "agents" at Baldwin Hill Mall in Los Angeles in what can only be described as a flash mob musical. It is absolutely hilarious.
