A young boy says to his father, “Dad, our math teacher is asking to see you.”
“What happened?” the father asks.

“Well, she asks me, ‘How much is 7 * 9?’ I answer ’63’. Then she asks, ‘And 9 * 7?’ so I asked, ‘What’s the difference?’”

“Indeed, what is the difference?” asks the father. “Sure, I’ll go.”

The next day, the boy comes home from school.

“Dad, have you gone by the school?” he asks.

“Not yet.”

“Well, when you do, come and see the gym teacher also.”
“Why?” asks the father.

The boy explains, “Well, we had a gym class today, and he asked me to raise my left arm. I did. Then my right arm, I also raised it. Then he asked me to lift my right leg, so I did. ‘Now,’ he says, ‘lift your left leg,’ so I asked, ‘What, am I supposed to stand on air?’”

“Exactly,” says the father. “Alright, I’ll come.”

The next day, the boy asks his father, “Did you go to school?”

“No, not yet.”

“Don’t bother, I got expelled.”
