Parks and Recreation is ordinarily a pretty wholesome show. Its humor can be somewhat biting - such as how Jerry gets treated - but overall it generally comes across as good, clean fun. In first season finale episode, entitled "Rock Show" the main character, Leslie Knope, is set up on a blind date with a 62 year old city manager of a neighboring town. Leslie thinks the dinner is a business meeting and only discovers partway through that George believes it is a date.
