Quinn is a minor bully in the 2003 film, Cheaper by the Dozen. He picks on Mark Baker for wearing glasses, which is the same reason the other Bakers pick on Mark. He is played by Cody Linley.
He does not appear early in the film like the other antagonists of the film. He appeared when Mark comes to school and bumps into him and another bully. The other bully pulls off Mark's glasses and he and Quinn laugh.
However, upon hearing of the incident, several of Mark's siblings confront Quinn and beat him up and get sent to the principal's office as a punishment.
