The best part about this video is it occured at an Ohio State/Northwestern game in Evanston.
Btw, if you didn't laugh at the mascot video you seriously need to lighten up. It was amazingly funny.
It's not like the Bobcat was beating the crap out of Brutus. He brought him down, then Brutus got up and he followed him into the endzone and the Bobcat jumped on him again, and while they were on the ground he threw some playful "punches" (and they weren't punches) in on him.
Saying that was assault is an insult to assaults everywhere.
