Little Joey returns from school and says he got an 'F' in arithmetic.
'Why?' asks the father?'
'The teacher asked 'How much is 2 x 3', I said '6' replies Joey.
'But that's right!' replies the father.
'Yeah, but then she asked me 'How much is 3 x 2?', states Joey.
'What's the fg difference?' asks the father.
'That's what I SAID!!' shouts Joey.
