The Twits is one of his many successful and highly entertaining books. The Twits are a couple that nobody would like to know. They are hairy, dirty, smelly and generally unpleasant. Roald Dahl's characters are possibly the most horrid people you will ever read about. Mr and Mrs Twit spend their days inventing new ways to be be nasty to each other. Each time Mrs Twit does something bad to Mr Twit, he just invents something worse to do to her. The Twits are not only unpleasant towards each other but they also hate animals. It is because of the Twits' attitude towards animals that we see their really awful side: Mr Twit keeps a family of monkeys that have to spend their days upside down and Mrs Twit likes to make pies with freshly caught birds.
