The difference

Little Jimmy comes home from school one day with his head hanging low and a dejected expression. His father asks, "What’s the matter with you, boy?"

"My teacher gave me an F in math today," Jimmy says.

"Why? What happened?" asks the father.

"I don’t know. First she asked me what 2 times 3 is. I told her 6."

"But that’s correct, son!" says the father.

"Yeah, but then she asked me what 3 times 2 is."

"Well what the fuck’s the difference?" demands the father.

"Yeah," agrees Jimmy, "that’s just what I told her."
