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 a few weeks off, explains the man. Im pretending to be nuts. Just then the boss walks by and sees the man dangling from the ceiling. What are you doing? asks the boss. Im a light bulb, answers the guy. Youre going crazy. Take a vacation. The man jumps down to leave, and the blonde starts to follow him. Where do you think youre going, young lady? the boss asks. Home, she replies. I cant work in the dark.
