This a few months back, but it's now starting to make the rounds on the internet! High school students in Collierville, Tennessee tricked their teacher into thinking they broke the TV in their classroom. They used technology to airplay the image on the screen making it appear to be broken.
The video starts with the teacher outside the room as a student throws a random chair to make noise. The teacher comes in the room and sees the TV & that's when he flips out.
