Submitter: The inside flap says that Fuller amassed the “most popular, most challenging (most irritating?) games for his delightful new book.” Library staff who examined this book agreed with most irritating. The book had not left the shelves in at least eight years. It’s a mystery how this book managed to escape previous weeding attempts, but its days are numbered!
Mary: I guess the “joke” is that if you can’t sleep, these puzzles will frustrate (torture) you until you fall asleep. The other theory is that it will turn you into an insomniac since you just can’t fall asleep because these puzzles are interesting. I am going with option one.
