Light-bulb

Susan was desperate for a few days off from work. But she knew that the boss wouldn't let her take a vacation. So she got a crazy idea. She hung upside down on the ceiling until the big guy noticed and asked her what she was doing. "I'm a light-bulb," she told him

"You are clearly stressed-out," said the boss, looking concerned. "Go home and take it easy for a couple of days." Susan jumped down and headed for the door. Her co-worker Janice seized the opportunity and followed Susan.

"where do you think you're going?" the boss hollered after her.

"I'm going home, too," Janice said. "I can't work in the dark."
