Exactly what I said

One day, Jack comes back from school and says to his father:

"Dad, today I got an F at Literature."

"Why, Jack?"

"Well, the teacher told me to say a poem and I said that poem you taught me: 'Sex is good / Sex is fine / Doggy Style & 69'."

"And she gave you an F for that?"

"Yes, dad!"

"Don't mind her, kid... Teachers these days don't know anything."

Next day, same story:

"Dad, today I got an F at Maths."

"Why?"

"Teacher asked me first 'How much is two times three?' and I answered 'Six'. Then he asked me 'How much is three times two?'"

"What the fuck is the difference?"

"That's exactly what I said..."

Next day, Jack comes home again after school and starts crying:

"Daaaad, they kicked me out of school."

"Why, Jack?

"My supervisor asked me to come and meet him after school hours. When I got there, besides him, there were 3 of my teachers: literature, maths and geography."

"What the fuck was your geography teacher doing there?"

"THAT'S EXACTLY WHAT I SAID!!!"
