Gillette Stadium wasn’t a house of harmony Monday Night.

That’s because a few Patriots fans fought each other in the upper deck of Gillette Stadium during their team’s 30-23 win over the Baltimore Ravens. What started as a minor disagreement over the city of Baltimore’s qualities soon escalated into a brawl, which involved both men and women.

An Instagram user shared the initial, um, discussion.

Booze might have helped the situation turn into this. It probably goes without saying, but there might be some language that’s just a little bit unsafe for work.

Those people obviously hadn’t watched enough episodes of “The Wire.” Otherwise, they’d know all they needed to know about how great Baltimore is, right?
