It seems everyone in that classroom recording including the teacher have forgotten the first rule of fight club.

A high school teacher in Texas has been suspended after recording a fight between students instead of stopping it.

The teacher from McKinney High School in McKinney, Texas, is on administrative leave after a video surfaced of him recording a school fight, according to the school district.

The video shows two unidentified students fighting while the male teacher stands back and films the interaction on his phone.

The incident was reported to the school district on Wednesday and the teacher was put on leave until officials could investigate the matter.
