One in a series of humorous books about disgusting creatures, The Rat is a look at the black rat. It covers such topics as the rat's long, agile tail (it's good for balancing and picking noses), long teeth (they can chew through anything, including books) and disgusting taste in food (delicious electrical wires in tomato sauce, anyone?).
