"The word crap is actually another word that's very, very old. It was taken over from 17th century England by the pilgrim fathers and Americans were talking about things being crap in the 17th and 18th centuries. What Sir Thomas Crapper – complete coincidence – does is not invent the flushing toilet, as many, many people believe, but was a great promoter for it. He ran a business marketing other people's products and that's why his name was on them. When the American soldiers came over in the First World War, they all thought it was hilarious that it said 'crapper' on them."
