Marvin Redpost is shunned by his classmates, best friends, and teacher after he is unfairly fingered as a nose-picker by the class bully.
Marvin inadvertently gets on bully Clarence’s bad side and Clarence accuses Marvin of being a nose-picker. The more Marvin denies the designation, the more his classmates ostracize him until even his two best friends no longer associate with him for fear of being lumped into nose-picker category and the social outcast status that came with it. With help from his family, Marvin uses a class survey assignment to put the question of whether they had picked their noses to his classmates, principal, and teacher and turns the table on his tormentor.
