A touch of humour: Little Johnny Jones joke.

In the English literature class, the teacher asks this question: "What was the name of Shakespeare's wife?"
No pupil seems to know the answer. Suddenly, Little Johnny Jones puts up his hand and says: "I know, Sir: It was Mrs Shakespeare."

Note: Shakespeare' wife's name was Anne Hathaway.
