Little Johnny came home one da…

Little Johnny came home one day and told his dad he had a tough day in math.
“What happened?” asked his dad.
“The teacher got mad at me.” Little Johnny grumbled.
“What for?” his dad asked.
“She asked me what 2 x 3 was. I told her 6.”
“Well, that’s right.” Said the dad.
“I know.” Said Little Johnny.
“But then she asked me what 3 x 2 was.”
“Christ! It’s the same fucking thing!” Cried the father.
“I know! That’s exactly what I told her,” huffed Little Johnny.
