Much of the humor derives from situational elements, such as encounters between Kintaro and the women gone awry, and interactions between Kintaro's libido and imagination. Recurring gags include Kintaro's fetish for toilets (especially those recently used by beautiful women), his exaggerated facial expressions, and comical entries in his notebook. The notebook entries include explicit drawings of the women he encounters and bits of wisdom such as "'C' base is not sex", and "The human head cannot turn 360 degrees." Regarding the series, Tatsuya Egawa writes: "Before leaving kindergarten, I wrote these words in my notebook: 'I really like to study.' Often I wonder when it was that our schools forgot the true meaning of 'study.' Something which is now so often misunderstood by teachers and parents. Learning ought to be both stimulating and entertaining."
