"Learning Addition" joke
A little boy was sitting at the kitchen table doing his math homework. He said to himself, "Two plus three, that son of a bitch is five. Three plus four, that son of a bitch is seven... "
His mother heard what he was saying and gasped, "What are you doing?"
"I'm doing my math homework, mom," he replied.
"And is this how your teacher taught you to do it?" the mother asked.
"Yes," he answered.
Infuriated, the mother went to see his teacher the next day. "What are you teaching my son in math?" she asked the teacher.
"Right now, we are learning addition," the teacher replied.
"And are you teaching the children to say two plus two, that son of a bitch is four?" the mother inquired.
Hearing this, the teacher burst out laughing. Once she regained her composure, she said, "What I taught them was, two plus two, THE SUM OF WHICH, is four."
