One of our favorite 5 year olds, Harper, has taught us some zinger knock-knock jokes over the past year and a half or so, and reminded us of our all time favorite. This is our first design specifically aimed at amusing the kiderati; however, we did do some in adult sizes to appeal to the kid in all of us.
