The woman says, "I can the boss give me the day off."
The man replies, "And how would do that?"
The woman says, "Just and ." She then hangs upside-down from the ceiling.
The boss 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 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 in the dark."
