Billy-Bob returns from school and tells his father he got an “F” in Arithmetic today.
“Why?” asks his father.
“The teacher asked, ‘How much is 2 x 3?’ I said, ‘6’”.
“But that’s right,” said his father.
“Then she asked me ‘How much is 3 x 2?’.”
“What’s the fucking difference?” asks his father.
“That’s what I said!”
