Little Johnny, the magician's son
"What's your father's occupation?" asked the schoolteacher.
"He's a magician, ma'am," said Little Johnny.
"How interesting. What's his favorite trick?" asked the teacher.
"He saws people in half," answered Little Johnny.
"Wow! That must be amazing to watch," said the teacher. "Do you have any brothers or sisters?"
And Little Johnny said, "One half brother and two half sisters."
I saw a magician who could make anything weigh exactly 28.3 grams.
His stage name is "The Wizard of Oz."
