Catbert: The one called Dilbert is showing signs of happiness at work. Boss: That means we can give him more work and he won't quit. Excellent. Is anyone else exhibiting signs of unauthorized happiness? Catbert: No. Everyone else is in the narrow band of misery you want them to be in. If they were any happier, it would mean you're overpaying them. If they were any less happy, the would take their own lives. If you don't hear any laughing or screaming, it means you're doing something right. Boss: What about moans? Catbert: Moans are ideal. That's the sweet spot.
