Little Johnny returned from school and told his father
that he'd gotten an "F" in arithmetic.

"Why?" asked the father.

"The teacher asked me 'How much is 2 x 3?' I said '6'",
replied Johnny.

"But that's right!" exclaimed his father.

"Then she asked me 'How much is 3 x 2?'",
explained Johnny.

"What the f***'s the difference?", asked his father.

"That's what I said!!", replied Johnny.
