And the Music Speaks Puns

I was in music class today and my teacher picked up a folder a pupil in the previous class had left behind. The folder was labelled 'French' and on top of it there was a book that said 'Speaking Book' (obviously referring to French Speaking practice).

My music teacher then opened the book and put it to his ear. With a confused look on his face he exclaimed: 'Well I can't hear anything!' Groaning from all the class then ensued.
