This is what you get for inviting Batman over for Christmas, though to be fair I'm not sure they actually invited him. Then again, maybe they should have expected that the Dark Knight would drop by at some point—this has apparently happened to them before.

Remember Max, the kid who terrorizes his mother as Batman in the video below? It seems the Batman ruining Christmas is the same Max, only a few years older and probably coursing with pubescent hormones, to boot. That might explain why he's even more aggressive now.

One thing to note: I'm pretty sure Youtuber TVMaxwell's take on the fight choreography here is legitimately better than Batman's actual fights with Bane in The Dark Knight Rises.
