Gone are the days when teachers could rule their classrooms with an iron fist. 

A teacher in Russia brought a student to the front of the classroom, then berated her—according to translators—for not understanding the material on the board. The student took the rant in stride. But the ordeal went south once the teacher got physical. 

After poking the girl in the head several times, the girl knocked his hand away and delivered a swift kick to his balls. If you thought it was funny enough to see him get what was coming to him, it's even better in slow-mo.
