A little boy comes home from school and tells his father, "I got an F in math today."

His father replies, "What happened?"

The boy says, "Well, my teacher asked me, 'What's 3 times 2', and I said '6.'"

The father replies, "Well, that's correct."

The boy says, "I know. Then she asked me, 'What's 2 times 3.'"

The father then replies, "Well, what the fuck is the difference?"

The boys says, "Well that's what I said!"
