Watching this video makes me feel like I'm in elementary school again. The London Knights and Peterborough Petes are currently involved in a third-round playoff series in the Ontario Hockey League. Things were getting rough during the last game, and the Knights' Ryan Humphrey was sent to the penalty.
While he was in the box, Humphry refused to sit down, instead standing at the door running his mouth and hitting the glass. The timekeeper, a much older man than Humphrey, had enough. He got Humphrey to sit down, and then game him a lecture that would make a 1960s school teacher proud, even putting his finger in Humphrey's face a couple of times.
