There are a lot of episode titles that have several meanings decribing different aspects of the story. Sometimes they are not that obvious and one might miss them. Here is the occasion to discuss such titles what they mean and why you like them. I will start with one: TNG "Lessons": Picard receives lessons in music and in leadership. Engaging in musical duets with other crewmen shall/will not interfere/conflict with his job as captain while playing duets in the sack might very well do so. This is the (non-musical)lesson he learns during this episode that I like very much.
