The group was part of Improv Everywhere, an organization dedicated to putting on lighthearted pranks involving hundreds of participants.

Improv Everywhere even went so far as to ask a local actress to portray an NBC reporter and conduct interviews with store employees. As one passer-by remarked, "Only in New York."
