How does Chapter 24 describe the unique nature of Sai Baba's humor and jokes?

According to Chapter 24, Sai Baba's use of humor was extraordinary and deeply loved by his devotees. Unlike ordinary jokes that people might dislike being the subject of, Baba's humor was eagerly craved. This was because he used it as a vehicle to impress the essence of truth in a way that was beneficial to all. The chapter describes his method as effortless and natural, delivered with a smiling face and playful eyes. When his gestures and acting were combined with the joke, the purpose was immediately achieved, and its sweetness became indescribable.
