Cacography is deliberate comic misspelling, a type of humour similar to malapropism. But Roche was not uttering a malapropism here, he was quoting, and quoting correctly. The worker then apologised for his ""Miss-Marple-ism"" (i.e., "malapropism"). He was also known by the nickname "Bones", which is a malapropism for Balboni. This broader definition is sometimes called "classical malapropism", or simply "malapropism". Ring Lardner used malapropism extensively for comic effect. Malapropism was one of Stan Laurel's comic mannerisms.
