This is priceless for several reasons. The story is pretty brief, but it's the comments that make it worth reading.
Watch how the angry and self righteous comments gradually turn from targetting the teacher to the student once they realize that it's a hoax. If half the people who claimed to send hate mail to the teacher actually did so, he or she has a lot of reading ahead. I bet less than a tenth of them bothered to apologize once they realized they were wrong too.
