"WARNING: This book is not for children of any age." So begins K is for Knifeball, the disturbingly funny new book from the creators of the equally macabre All of my friends are dead, which has also been accompanied by one of the darkest book trailers we've ever seen.
Thanks to Chronicle Books, we have some of the book's terrible advice here to share with you, including the things not to say to Grandma, the illustration for which can be seen being made in the video above.
Just don't try any of this at home. Ever.
