Book excerpt: Old Macdonald loves his phone: it helps him organize his farm. But when the animals each get one of their own, they are soon on their phones all day—"Here a tweet, there a chat, WhatsApping the farm cat"—and before they know it, no work is getting done! What can Old Macdonald do? Sing along to the tune of "Old Macdonald Had a Farm" and see! A hilarious cautionary tale for a new generation of phone-users, from the award-winning partnership of Jeanne Willis and Tony Ross.
