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."
