One day

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 were 3 of my teachers: literature, maths and geography.
What the fuck was your geography teacher doing there?
THAT'S EXACTLY WHAT I SAID!!!
