Little Johnny's tough day in maths class

Little Johnny came home one day and told his dad he had a tough day in maths class.

Dad: "What happened?"

Little Johnny: "The teacher got mad at me."

Dad: "What for?"

Little Johnny: "She asked me what 2 x 3 was. I told her 6."

Dad: "Well, that's right."

Little Johnny: "I know. But then she asked me what 3 x 2 was."

Dad: "OMG! It's the same IDIOT!"

Little Johnny: "I know! That's exactly what I told her!!!"
