Little Johnny was doing his math homeworl ""One plus one, that son of a bitch is two. Three plus six, that son of a bitch is nine."" He says to himself. His mother over hears him and asks what he's doing. ""My math homework."" He says. ""Is that how your teacher told you to do it?"" Little Johnny nods. The next day the mother talks to the teacher. ""Are you teaching my son to say. 'Two plus two, that son of a bitch is four.' ?"" ""Oh no!"" Says the teacher, ""It's, 'Two plus two, the sum of which is four!'""
