Math Homework

A young girl came home from school and was heard by her mother reciting her homework: "Two plus two, the son of a bitch is four; four plus four, the son of a bitch is eight; eight plus eight, the son of a bitch--"

"Judy!" shouted her mother. "Watch your language! You're not allowed to use swear words like son of a bitch"

"But, Mom," replied Judy, "that's what the teacher taught us, and she said to recite it out loud till we learned it."

Next day Judy's mother went to school with her daughter and right into the classroom to complain. "Oh, heavens!" said the teacher. "That's not what I taught them. They're supposed to say, 'Two plus two, the sum of which is four.'"
