Last year, we were charmed by a video of a jolly bearded man ("probably plunked here from the Andromeda Galaxy or West Coast") enthusiastically high-fiving people trying to hail cabs around the city. That man was Brooklyn-based actor and filmmaker Meir Kalmanson, who has followed up that video with his latest attempt at connecting with strangers and/or making strangers feel uncomfortable: dancing behind people (without them realizing it).

The best parts are obviously when the unsuspecting strangers have no idea what was just going on behind them, but fair warning to anyone who might be inspired by this video to try to spread joy in a bright green shirt: don't even think about pulling this shit near a cop. The Ellen Degeneres's #DanceDare challenge has never recovered.
