The latest on my list of must-see YouTube videos is an improv event from New York.
You take 200-plus people, turn up at Grand Central Station and at a predetermined time, everyone freezes on the spot for several minutes.
Then, like magic, they all start moving again at the same time. The reactions of onlookers are classic.
Maybe we should try that on Esk St on a Friday night just to confuse the hell out of the boy racers.
