According to Chapter 24, what was the unique nature of Sai Baba's humor, and why did devotees love it so much?

Chapter 24 explains that Sai Baba's ways were extraordinary, as he would impress the essence of truth even through jokes, which was beneficial to all. Unlike typical humor that people might dislike being the subject of, devotees craved Baba's humor and would eagerly wait, wondering when it would be their turn. This was because his humor was effortless, novel, and natural. The chapter states that when combined with his gestures, a smiling face, and playful eyes, the purpose was immediately achieved, and its sweetness became indescribable.
