Quote from Sophia in Take Him, He's Mine
Sophia: Why do we have his IOU for two bucks? Rose: Well, he didn't have anything smaller than a hundred and we didn't have change. Sophia: What about these? Rose: They all had hundreds, too. Sophia: Rose, let me give you a few lessons in economics. Lesson number one: Quit being an idiot. Rose: OK. Sophia: Lesson number two: The law of supply and demand. Before you supply sandwiches, you demand the money. Rose: OK. Sophia: Lesson number three: Quit being an idiot.
