Mr. Devlin

Mr. Devlin (born June 12, 1953) is a history teacher at Ridgeway High School. He is known for being very strict to his students, even in his former position as the lunchroom montior from 1988-2000. He also hates 3-hole punched paper, as revealed to Carly in the episode "IPromise Not to Tell", when he keeps Carly from getting straight A's by giving her a B+ on a history paper.
