Which reminds me of an old joke: A guy sees a lunch counter with a sign in the window, "Orange Juice - All you can drink for 10 Cents." He walks in and orders a glass of orange juice. The guy at the counter produces a tiny juice glass and fills it up. "Ten cents," he says. The guy pays, drains the glass, and says, "Fill it up again." The guy at the counter says, "Okay, but that'll be another ten cents." The guy says, "Wait a minute -- your sign says 'All you can drink for ten cents.'" The guy at the counter says, "Right. And that's all you can drink for ten cents."
