In this chapter, we learn that we can learn another kind of martial art, called "Kung Fu." We learn that it's called "mum knock - down." We also learn that this is the same martial art that we learned in the previous chapter, "Mother-Knock-Down." This time, we're going to learn "direct knock-down," which basically means, "You can hit me with whatever you want, but I'm not going to let you do it before I've knocked you out." This is a pretty important lesson, because if you want to fight someone, you've got to do it in a way that's going to get you knocked out. This is the first lesson we've seen in this chapter. We're not really sure what this lesson is all about, but we'll find out soon enough.
