Teaming up once again with their partners-in-pranking at the Guggenheim Museum, Improv Everywhere agents and volunteers hit a shopping center parking lot in Staten Island to take part in the troupe's latest mission: Car Alarm Symphony.

One hundred car alarms were switched on simultaneously using the concealed participants' remote "panic" buttons. As you might imagine, things got pretty loud pretty fast.

Luckily for shoppers (and probably for the participants), the "urban experiment" was "mercifully brief."
