Good One

A guy is hanging upside down from the rafters at a factory when a blonde coworker walks by. "What are you doing?" she asks. "I need some time off," says the man. "I'm pretending to be nuts." The boss walks in, sees the worker hanging from the ceiling, and asks, "What are you doing?" "I'm a light bulb," answers the man. "I think you need some time off," says the boss. So, the man jumps down and leaves. The blonde begins to walk out, too. The boss asks, "Where do you think you're going?" The blonde answers, "I'm going home. I can't work in the dark."
