Two factory workers were talking. "I think I'll take some time off from work." said the man. "How do you think you'll do that?" said the blonde. He proceeded to show her by climbing up to the rafters, and hanging upside down. The boss walked in, saw the guy hanging from the ceiling, and asked him what on earth he was doing. "I'm a light bulb" answered the guy. "I think you need some time off," said the boss. So, the man jumped down and walked out of the factory. The blonde began walking out too. The boss asked her where she thought she was going. The blonde answered, "Home. I can't work in the dark".
