Jeff urgently needed a few days off work, but knew the Boss would not allow him to take a leave. He thought that maybe if he acted crazy then the boss would tell me to take a few days off. So, Jeff hung upside down on the ceiling and made funny noises. His co-worker Cathy (who's blonde) asked him what he was doing?
He told her that he was pretending to be a light bulb so that the Boss would think he was nuts and give him a few days off. A few minutes later the Boss came into the office and asked "What are you doing ?" Jeff told him he was a light bulb. The boss said "You are clearly stressed out. Go home and recuperate for a couple of days". Jeff jumped down and walked out of the office. When Cathy followed him, the Boss asked her: "
And where do you think you're going?
She said, "I'm going home too, I can't work in the dark!"
