"Santa and Mathematics !" joke
This was when Santa was a little boy studying in a convent school. He was busy doing his homework and 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.
Santa remarked that his teacher had taught him. His mother was rather upset and told him to stop the homework. The next day she stormed into little Santa's classroom and confronted the teacher. She told her about Santa's different way of doing math and his claims that she taught it that way to the class.
The teacher was flabbergasted. She said that she couldn't understand why Santa had said what he did.
Then suddenly, she exclaimed, "Oh, I know... here in school we say, one and one, the sum-of-which is two..."
