"Going by the Book" and "Boyhood" have different plots, but they're similar for being a unique comedy where the main charactes are randomly assigned to a certain role and how they took it seriously and so on to the series of misunderstandings with other people.

A boy who pretends to be this well known delinquent, but in reality he cannot fight. He is a loser who was constantly bullied and beat up. They both similar because both main characters pretend to be delinquents or tough fighters. It is also similar because both of these are very comedic school fighting dramas.
