　　In a certain school there was a young fellow who caused all sorts of trouble. He talked back to his teachers, he refused to do his homework, and he was disrespectful to everyone.

　　Finally, the school master decided to call the young man's father.

　　The father came to the school to see the master and the two of them discussed lots of problems the young fellow was causing. As the master was talking, the telephone rang. He excused himself to the parent and answered it. The person on the other end wanted some information.

　　“Certainly,”said the master. “I have it right here in my desk.”He reached for the desk drawer and opened it. There, much to his surprise, was a big, red book with the name“The Dirty Joke Book”.

　　The father of the student was astonished when he saw the book! “Well, sir,”he said to the master,“I suggest you practise what you tell the students to do!”

　　As it turned out, the master had taken the book from a student, put it in his desk drawer, and he had completely forgotten about it!

　　Needless to say, the master had a lot of explaining to do.
