(It will be easier to understand if you know a bit of spanish.) A mom told her son to buy some raspas. When the boy came back see said, "Vete a vender los ya no los nececito." So the boy started to sell them. The next day the mom wanted some melons so the boy bought them. Then his mo said the same thing, "Vete a vender los ya no los nececito." So the boy started to sell them. The next day the mom wanted eggs so the boy bought eggs and came back home to the same story. So the boy sold them. One of his friends help him seel them but he didn't know much spanish so he said, "Rascas, Melos, Uevos."
