I remember being in school and kids talking back to their teachers but it was always snarky remarks (I was a pretty good student so I never got in trouble). One Texas student decides to take his exit from the class as an opportunity to tell his teacher what he REALLY thinks and it makes a lot of sense.
There are a couple of cases of language that are NSFW, so watch with caution:
The student, Jeff Bliss, has gained the support of his peers and has been interviewed on the local news several times. The video has been pulled from Youtube several times since being published.
Would you defend yourself to a teacher like this?
