What is going on here?

This video of a woman riding an escalator from 2012 is blowing up on LiveLeak and while I don't know whether it's okay to find this funny (it seems like she would be fine?) it's still a really great reminder that you should never just hold on to the escalator rail and do nothing else. Those things have the strength of hundreds. (It's also why my partner will never stand on the same escalator stair as me.) (Also because he is embarrassed to be seen with me.)
