We Need More Teachers Like This!

First off the world needs more teachers like this who aren't afraid to tell it like it is and give the straight truth. Secondly, what the hell is wrong with the students in that classroom?! I'm embarrassed to be a part of this generation of people who think that behavior like what is displayed in that video is acceptable. I don't care what you've been through in life nor how your parents raised you there is no excuse for the actions that took place in this video and 90% of the other things people do nowadays. EVERYBODY knows the difference between right and wrong.
