So we'd say things like, let's agree that you're going to sell 57 widgets per week. If you sell them by Wednesday, please go to the beach. Don't create a problem for us, for manufacturing, for application, then we have to buy new companies, we have to buy our competitors, we have to do all kinds of things because you sold too many widgets. So go to the beach and start again on Monday.
