Little Johnny was overheard by his mother reciting his homework, “Two plus two, the son of a b*tch is four; four plus four, the son of a b*tch is eight; eight plus eight, the son of a b*tch...;” “Johnny!” shouted his mother. “Stop swearing!” “But mom!” Little Johnny protested, “That’s what the teacher taught us! And she said we should recite it till we learned it!”
The next day his mother went to the teacher to complain. “No, no,” said the teacher, terrified. “That’s not what I taught them. They’re supposed to say: ‘Two plus two, the sum of which is four.’”
