Little Johnny was busy doing his homework. As his mother approached she
heard: "One and one, the son-of-a-bitch is two." "Two and two, the
son-of-a-bitch is four." "Three and three... "
His mother interrupted, asking where he had learned this way of doing math.
Johnny remarked that his teacher Ms. Clara Jones taught him. His mother was
rather upset and told him to stop the homework.
The next day she stormed into Little Johnny's classroom and confronted Ms.
Jones. Little Johnny's mother told Ms. Jones about Johnny's different way of
doing math and his claims that Ms. Jones taught it that way to the class.
The teacher was flabbergasted. She said that she couldn't understand why
Johnny had said what he did.
Then suddenly, Ms Jones exclaimed, "Oh, I know... here in school we say, one
and one, the sum-of-which is two."
