No, My Darling Daughter 227 : Season 4 Episode 21

Lester hires a young ex-con from the persuasion on Mary. They both admit that he is doing a great job and are happy with him until he asks Brenda out. They object and eventually tell Mike that he is not allowed to see Brenda. He feels dejected and decides he may as well not take the GED test as planned, because people will always see him as an ex-con. The real Joe Clark of the ""Lean on Me"" fame comes and gives him words of encouragement and he decides to take the test. The Jenkins apologize for the way they treated him.
