...WHAT A TWIST.
Let's face it: In the same way we all have a zombie plan, our instincts are movie-honed for a secret-agent scenario -- as soon as these guys are given a destination and a countdown clock, the inner Bond comes out just as the train station turns into an obstacle course.
One of the coolest marketing stunts ever.
Sometimes, on quiet afternoons at Twitter HQ, a guy in a letterman jacket will start a flash mob.
Watch as tech geeks the lunchroom over rise up to join him in a choreographed dance to Justin Bieber's "Baby."
(Not Safe For ... Pretty Much Anything -- excessive use of the Biebs.)
