This couldn't have happened at a worse time.
YouTube prankster Alexander BOK decided to film a little video in NYC on Christmas Eve in New York as part of Ellen's #DanceDares challenge.
The idea is to record yourself dancing behind strangers without them knowing and possibly have your clip appear on the show.
So he tried this out in Grand Central Station where, for the most part, people were amused and there weren't any no major incidents.
But when he decided to start dancing behind some cops outside, things got a bit more serious.
"What's wrong with you bro?" one of the cops asks in the video, as four officers approach the prankster.
Alexander BOK explains the purpose video to them, and they proceed to call him an "fucking a**hole" and eventually pushing him away, knocking him to down on the ground.
The NYPD is investigating the incident, according to TMZ.
