Jack Dannism

A Jack Dannism is an instance where a book's title and author can be joined to form a comprehensible sentence or phrase.

Science fiction editor Gardner Dozois is credited with making this discovery when he noticed that Jack Dann's book The Man Who Melted could be put together in this way to form "The Man Who Melted Jack Dann".

While it is agreed that it is acceptable to allow existing words to change parts of speech (e.g., "The Wolves of Willoughby Chase Joan Aiken"), there is disagreement about whether tinkering with punctuation is allowed. For instance, opinions would differ on whether to allow the apostrophe to be removed from Harry Potter and the Philosopher's Stone to form "Harry Potter and the Philosophers Stone J. K. Rowling".
