Sarah Steps Out

S3, E14: Charles is ecstatic he received an "A" in his worst subject, Creative Writing, until he learns that he accidentally switched papers with Sarah for her English class. Sarah tells Charles that her teacher thought the paper was so bad she gave her a C minus and threw it out. Charles is in an ethical quandary: if he does not pass the course, he could lose his student loan because of a low grade point average. He decides to explain the misunderstanding to Sarah's teacher -- but not to his professor. Buddy is stunned and disappointed by Charles' cover-up and keeping a grade he did not earn.
