A little boy was doing his Math homework. He said to himself, Two plus five, that son of a bitch is seven. Three plus six, that son of a bitch is nine...
His mother heard what he was saying and gasp, What are you doing ?
The little boy answered, I'm doing my math homework, Mom.
And this is how your teacher taught you to do it ?
Yes, he answered. Infuriated, the mother asked the teacher the next day, What are you teaching my son in math ?
The teacher replied, Right now, we are learning addition.
The mother asked, and are you teaching them to say two plus two that son of a bitch is four ?
After the teacher stopped laughing, she answered, What I taught them was, two plus two, THE SUM OF WHICH, is four.
