YouTube is doing a Geek Week, celebrating and discussing all things geeky. The Nerdist channel has already given us the hilarious Patton Oswalt Filibuster in animated form but now they have given us something even more awesome: Grammar Slam.

WWE wrestler CM Punk (Yes, that's his wrestling name) have graciously decided to teach the world correct grammar by reading tweets and letter that people have sent to him and pointing out their mistakes and teaching them how to fix it. Unfortunately, CM Punk suffers from nerd rage. Observe! HEAD'S UP: He uses strong language due to the nerd rage and language of the fanmail.

Apparently, he actually does this on his twitter feed which makes me love him a little bit. CM Punk, trying to help the trolls, one grammar lesson at a time
