Mr. O'Connell, full name Casey O'Connell, is a chemistry teacher that teaches Chemistry and Chemistry H at Gunn High School commonly known more for shocking statements than teaching chemistry. Most students consider him to be a worse Chem H teacher than Dr. Mellows since he does not give instruction on course content and students are less likely to achieve a more desirable letter grade in his class since summative assessments are weighted more than usual.
