A customer sits across from Dogbert's desk. The boy says, "I've failed the driving test nine times. Can you help?" Dogbert replies, "I specialize in the problem cases. Just sign the application form." The boy looks at the pencil and says, "Wait . . . I've seen one of these before. Yes, there's something special about the pointy end . . . But what?" Dogbert thinks, "Uh oh."
