Jane and Bill are working in an office and Jane says "I don't feel like working today". She saw the boss coming so she jumped up and hung upside down from the rafter. The boss asks "Jane what are you doing? "She says I'm a light bulb". The boss says "Ok Jane I thing you better go home". As Jane is walking out Bill is right behind her and the boss yells "Hey Bill, where do you think you're going?" Bill yells back "If you think I'm working in the dark you're mistaken".
