S1·E9 Corky Witnesses a Crime

Corky tries out for the football team. The footbal coach hits a student, one of his former players, and all the team stands up for the coach except Corky who is compelled to tell the truth. The coach claims that he was hit first. He cuts Corky from the team, but later when the team comes out with truth as well, Corky is allowed to keep trying out.
