A secretary goes to the company stockroom and requisitions a box of pens. The clerk fumbles around for a bit and then hands her a box of ballpoints. The secretary returns to her desk, takes out a new pen and begins to write. The pen skips and then stops giving out any ink. Frustrated, she tries another pen and then another and another. None of them work. Returning to the stockroom, she slams down the box of defective pens and demands, "Why did you give me a box of pens that don't work?" The clerk answers, "Well, somebody has to use them!"
