Little BILLY returns home from school and says he got an F in arithmetic.
"Why?" asks the father."
"The teacher asked, 'How much is 2x3?' I said 6," replied BILLY.
"But that's right!" says his dad.
"Yeah, but then she asked me, 'How much is 3x2?'"
"What's the f***ing difference? " asks the father.
"Yeah! That's what I said!"
