I think I remember the green you are talking about. It's about teaching a nigger how to farm and use fertilizer. This nigger has crops multiple times better than any other nigger. The nigger is taught how to save money from one season to purchase supplies for the next season. As soon as white man leaves the nigger spends all the money from the previous season on ridiculous things that have no value. Another story is how a nigger cannot plan for the future. You pretend they find a banana tree with bananas for everyone and even more. Not one of them thought "let's put a banana in the ground to grow another banana tree". They would consider the "person" who does that stupid and should be killed for wasting a banana.
