Two factory workers are talking:
The woman says :"I can make the boss give me the day off."
The man replies, "And how you are gonna do that?"
The woman says, "Just wait and see." She then hangs upside-down from the ceiling.
Their boss comes in and says, "What are you doing?"
The woman replies, "I'm a light bulb."
The boss then says, "You've been working so much that you've gone crazy. I think you need to take the day off."
The man starts to follow her and the boss says, "Where are you going?"
The man says, "I'm going home, too. I can't work in the dark."
