Forever immortalised in the minds of Roald Dahl's fans, Mr and Mrs Twit are a grotesque couple of animal haters that receive a typically gruesome comeuppance.
But in 2023, should this awful fictional pair continue to be described as "ugly and fat"?
Not according to Dahl's estate and publisher Puffin, who are working together to remove offensive language and update all of Dahl's books in line with modern day sensibilities.

What changes are being made and why?
Puffin Books have hired sensitivity readers to remove offensive language and replace or update old-fashioned terminology.
According to The Guardian in the UK, most of these changes relate to the physical appearances of characters. The words "fat" and "ugly" have been removed from every new edition of Dahl's books including The Twits. Chocolate lover Augustus Gloop from Charlie and the Chocolate Factory is now described as "enormous" as opposed to "enormously fat".
Anything racist such as the phrase "weird African language" in The Twits has been replaced by "African language", and words like "crazy" or "mad" have been removed to reflect modern attitudes to mental illness.
