We just received this book and already have been having a lot of fun with it! The jokes are appropriate for an entire family - even young children will find many of the jokes funny. Some of the jokes just make you smile, while others make you laugh til it hurts. My kids (ages 8, 10, and 12) enjoy telling jokes and they have been reading through this book on a daily basis to find new favorites. My youngest enjoys the play on words the most - for example, "How do you put a baby astronaut to sleep?" (Rocket). Or "What did the baby light bulb say to its mother?" (I wuv you watts and watts). The book is broken down into different categories/chapters, so you can find jokes and riddles easily. Overall, I think this is a fun book to have around the house for kids to peruse.
