'A boy goes to school wearing a bird cage on his head. He explains to his teacher that it is a self-imposed punishment because he blames himself for the murder of his girlfriend's budgerigar, only to find out that the budgerigar had already died before the boy's dog played around with it. The only short story from this book not to be adapted into an episode of Round the Twist'   (https://en.wikipedia.org/wiki/Unbearable_(short_story_collection))
