It’s called Evolution of Dance, and it is the highest viewed video on Youtube, at time of writing it had 125,689,850 views. To my amazement it even has 392,591 comments!
The age counter tells me it’s about three years old, with some dodgy high school maths I put that at a staggering 114,785 views per day for the last three years to hit that many total views.
It feels like something fishy is going on, check out the video for yourself (maybe now we’ve found out why it has so many hits?).
