One day, Jack comes back from school and tell to his father..

Dad, today I got an F at Literature. Why, Jack? Well, teacher told me to say a poem and I said her that poem you had learned 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 did you get it? Teacher asked me first "How much is two times three?" and I ansered "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 hours. When I got there, besides him, there were3 of my teachers: literature, mathsand geography. What the fuck was your geography teacher doing there? THAT'S EXACTLY WHAT I SAID!!!
