The man dancing in the video above is Alexander BOK, a YouTube prankster who tried to perform a particularly risky version of Ellen DeGeneres' Dance Dare, where viewers submit videos of themselves dancing in public.
Of course, BOK, who describes himself as "Your Favorite Prankster," tried to take the dare to the next level by dancing in front of a few New York City cops, who aren't exactly in the mood for levity this decade.
After confronting BOK and calling him a fucking asshole, they throw him to the ground before walking away. TMZ reports that the NYPD is investigating the incident.
