S1E3 Sex and the Single Father

Jeremy, the son of Martin and Judith, is struggling academically due to his infatuation with his attractive female teacher. After the teacher reaches out to Judith about Jeremy's distraction, Judith shares the news with Martin. Attempting to have the "talk" with his son, Martin finds out that Jeremy is already somewhat knowledgeable but still has questions. To address his concerns, Martin visits the classroom, where he becomes captivated by the teacher's looks himself. This ultimately leads to Martin and the teacher going out for dinner together.
