The School Teacher - S4.E15

Danny goes to see Rusty's fourth-grade teacher, Miss Lorraine Andrews. He doesn't approve of her method of teaching at all. She, in turn, says that singing in a night club is much easier than teaching school. Danny challenges her to prove it, and she shows up to prove her point. The next day Danny brings her an apple as a peace offering, and they reconcile, but Danny manages to re-offend her yet again by minimizing the importance of her profession. After her emotional outburst, Danny writes ""I AM A DOPE"" repeatedly on the blackboard.
