D Train brawl nearly ends in no-pants ride

This is the baffling scene that unfolded on a New York City subway platform during the morning commute rush hour.
A cell phone video shot in Brooklyn's Atlantic Avenue-Barclays Center shows two men in a raging fight on the D-Train platform, while a sick woman lies just feet away.
'Just a regular morning commute,' says the individual who posted the video in March. 'Sick passenger putting the train out of service, and then a squabble before I even get my coffee.'
The video starts while the fight is well underway, and though the preceding events are unclear, it does not appear to be related to the sick passenger, who the two men fighting both ignore.
