I'm not a guy that is easily impressed, but Waterloo Blackhawks coach P.K. O'Handley made George Gwozdecky look like a total amateur with a world class on-ice hissy fit.
For the record, O'Handley's team won the game 7-4 despite O'Handley racking up a 2 minute unsportsmanlike penalty, a game misconduct for abuse of officials, and a gross misconduct.
My favorite part of the video is the guy holding the big sign that just said 'You Suck' at the end. That guy didn't know who, or when, but he had the faith that somebody, at some point was going to suck, and damn it, he was going to be prepared for that moment.
