Dotty delight. Hands up if you like laughing. TV hero Justin Fletcher brings you his first ever joke book for preschoolers. It’s a feast of giggles and gags specially created for small people. What should you wear when it rains? Thunderpants. What do gorillas sing at Christmas? Jungle bells. What book should you buy if you like a great chuckle? This one. You’ll love the cheerful colour pics almost as much as the jokes.
