He said to himself, "Two plus five, the son of a bitch is seven. Three plus six, the son of a bitch is nine."
His mother heard what he was saying and gasped, "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?" the mother asked.
"Yes," he answered.
So the angry 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, "But... are you teaching them to say 'three plus six, the son of a bitch is nine?'"
After the teacher stopped laughing, she explained, "Actually, what I taught them was, two plus two, THE SUM OF WHICH, is four."
