It was a regular day at first grade, and the teacher asked all the students to tell her something about what their parents do for a living. Some kids knew and gave a good description, while others didn't really understand their parents' jobs and gave vague descriptions or none at all. When they got to little Johnny, he stood up and said: "My dad cuts people in half." "Oh, really?" asked the teacher with a smile, "You mean he's a magician?" "I don't know." Said Johnny. "A surgeon, maybe?" asked the teacher. "I don't know." repeated Johnny. "Then why do you think he cuts people in half?" asked the confused teacher. "Because I have two half brothers and three half sisters."
