art of the dad joke (or as I like to call them, Mr. Harold jokes), then this volume is for you. This collection represents a lifetime of collecting, honing, improving, revising, improvising, and then retelling some of the worst groaners you could imagine! Embarrass your son at his next birthday party! Make your daughter cringe in the car when you chaperone a date! Make your wife blush at the next cocktail party! Basically, learn the art of being a dad!
