Allegedly, the fight started out merely as a heated discussion between an Orioles fan and a Yankees fan and then it escalated to physical contact, then punches. But one of the bizarre parts of the fight is that when the Orioles fan really starts to go crazy and just straight up punch the New York fan right in the face, the Yankees fan just randomly starts laughing.

Either way, whoever recorded the fight clearly was enjoying the front row seats to this fan fight.
