HILARY-TY WILL ENSUE WHEN YOU BEGIN READING THIS KNOCK KNOCK BOOK.
Noted Knock Knock Author Cam Smith takes you on a journey through the world of people knocking on doors and other people wanting to know who is on the other side before opening said door. It is just good security practice.
With a knock knock for every occasion - from dining on Death Row to travelling through time - you will never need another knock knock book.
