If Jersey Shore is any indication of life if New Jersery (and we're assuming it is), fighting is just what happens there and isn't that much of a big deal. But bear fighting? Well that's certainly novel.
A resident in Rockaway, New Jersey caught two bears fighting on camera back in August and the clip is only doing the rounds now because that's just the way bear fighting videos work. Allegedly these two male bears were fighting over a nearby female, but she never shows up in this video so we're just going to have to assume that these two are just duking it out for the craic.
In fairness, we've been to New Jersey and the only thing to do is go discount shopping or go to New York. And seeing as they're bears and can't do either of those, fighting is probably the next best thing they can do.
