Watch: 2 couples brawl at Cardinals-49ers game

There have been some ugly brawls in the stands of NFL games this season, including this one that broke out during Thursday night's game between the Arizona Cardinals and San Francisco 49ers.

Deadspin spoke to the person who filmed the video below, a guy named Emil, who said the fight started after the two women began arguing, which lead to their boyfriends getting involved. One of the couples was ejected, while the other left and then returned 20 minutes later to a round of applause and high-fives.
