James Allan Einstein has been collecting kids jokes of all kinds since.well.since he was a kid! In fact, he still thinks of himself as a great big kid because he still gets a kick out of grossing people out with vomit and bathroom jokes, and he also loves the quintessential Knock-Knock joke! Invariably, his friends will groan when he says excitedly, "I've got a new one for you!" This book of hockey jokes is especially close to his heart because hockey is his next greatest passion.
