Great video thats nearing two million views in less than a week.
Improv Everywhere pulls some fantastically creative stunts in and around New York City. I started following their pranks a few years ago after they showed up at the Mercury Lounge as superfans of a young band, the Ghosts of Pasha. Be sure to check out the rest of their online videos on their site.
Also, the popularity of their two latest pranks has generated a ton of traffic to their site. Consider donating to their cause so they can continue to share their creativity with us.
