Public transportation is supposed to be a wonderful thing, but this video makes it painfully obvious that riding the train isn't always a pleasant experience for every passenger.
In this short clip an older man is arguing with what seems to be a much younger male. As the situation intensifies the older individual attempts to lure his newly found adversary off of the train to fight him fairly.
In a split second of fury the younger individual decides that he doesn't want to wait until the train ride is over to fight the older man. He proceeds to deliver a violent punch to his elder, that results in an instant knockout.
Check the absurd encounter out above.
