South Park

In a school bathroom, a man with blonde hair and a blue shirt holds a young boy in a red shirt and green hat, slamming his head repeatedly into a cracked mirror above a sink. The man's face shows intense effort and anger as he pushes the boy's head forward and back against the mirror, while the boy's face shows distress. The scene loops, showing the continuous, violent action of the man forcing the boy's head into the mirror.
