điên đầu vì không hiểu ý nghĩa câu chuyện cười này

A progressive kindergarten teacher wanted her charges to learn about life through firsthand experiences. So after much red tape, she was able to persuade her superiors to let her take the class of all boys to a horse racing track to learn about the pitfalls of gambling. After they had been there a while, several of the children asked to go to the boys' room. She escorted them there under the guidance of a track employee who guarded the door for them. She saw to it that the boys had no problems and in some cases had to help them unbutton their trousers. As she moved helpfully down the line, she suddenly saw something that made her do a double take. "Are you only five years old?" she gasped. The object of her contentions replied, "What do you mean, lady? I am riding Dandy Charger in the third race."
