Your child groans that reading is boring but will laugh at anything. This is a shelf of the funniest books going. Any single one does the whole job on its own. Pick by your child's age and by what makes them laugh, comics, gross-out, a cheeky narrator, then hand that one over first.
Every child finds reading boring in their own way, so this is a shelf you pick from, and any one book is a complete answer. Match it to the laugh. For the youngest, or the child who won't face a page of text, start with a comic: Dog Man or InvestiGators, joke-a-panel and barely a paragraph in sight. For the one just stepping into chapter books, Miss Daisy Is Crazy! is tiny and cartoon-packed, and Clementine is a warmer, spirited-child comedy. The Bad Guys sits between comic and chapter book, all capers and gags. For a reader who's older or reads fine but says books are dull, the illustrated novels, Timmy Failure and The Terrible Two, are funnier and a touch longer, and The Twits is classic Roald Dahl at his most gleefully revolting. Read the flap or first page aloud, watch for the first laugh, and hand it over.
