Joey: Why are you so tired?
Chandler: I couldn't sleep last night. And then I started worrying about this big divisional meeting I have later today. The more I worried, the more I couldn't sleep. You know, and then I was, like, "If I fall asleep now, I'll get six hours' sleep. But if I fall asleep now, I'll get five hours' sleep." No matter what I did, I couldn't fall asleep.
Joey: You know what you should've done? You should have told yourself that little story.
