Not since an aged A's fan decided to fight all the cops have we seen a display of old-man badassery like this.

Reader Michael graciously sent along this video, which he took at this weekend's rivalry game between Arizona and Arizona State, and it is just the best damn thing. I mean, good god, just look at how perfectly executed that face kick is. That ASU bro probably thought he was in for a walk in the park when he started gettin' wise with the old man, and then BAM, foot to the face! Have a seat, youngster.

And the old man doesn't stop there! He stands tall and continues to throw haymakers at the now shamed-for-eternity ASU bro's shocked friends. We're just sorry that the video cut off before the elderly vigilante started picking up bros at random and breaking them over his knee, Bane style.
