Billy-Bob

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!"
