Something happens to a man’s sense of humor after he has his first child. Someone who was once witty and insightful, suddenly takes a turn towards corny puns and family-safe jokes. You can’t correct their path into the land of unfunny, so you may as well celebrate it by giving them some more ammunition for their dad joke arsenal. Expect to uncover some real gems in this book, ranging from classics like What’s brown and sticky? (A stick) – to the slightly confusing – How does an elephant get down from a tree? (He sits on a leaf and waits until autumn).
