Broken TV prank on teacher in class

Two guys pretend to fight while their teacher was out of the room. Right when he gets back one of the students casts a screen that shows a broken screen desktop onto the classroom television. They throw a chair on the ground and pretend to push each other. The teacher comes in and is surprised and asked who threw the chair and broke the tv. He gets angry and yells at them telling them how expensive it is. At the end he looks unamused from the prank
