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 portrayed by Cody Linley.
He does not appear early in the film like the other antagonists of the film. He appeared with another bully when Mark comes to his new school and purposefully bump into him and knock Mark's glasses off and he and the other bully laugh.
However, upon hearing of the incident, several of Mark's siblings confront Quinn and stand-up to him and the other bully by beating him up and get sent to the principal's office as punishment.
