Do you feel like laughing? Then you'd better not read this book! There's no laughing allowed! Not even any smiling, and if you think you might get away with a giggle, be warned, Mr Frimdimpny will be watching. If he spots a smile or glimpses a grin you will have to go back to the beginning and start all over again! Follow the rules carefully and see if you can reach the end of the book - it won't be easy.
