Little Johnny returned from school and saying he got an 'F' in Math.

"Why?" asked his father.

"The teacher asked 'How much is 2x3?' I said '6'"

"But that's right!", said his dad, upset at the injustice.

"Then she asked me 'How much is 3x2?'"

"What's the f*@#%! difference?" asked his dad.

Little Johnny replied "That's exactly what I said!"
