14. "Elementary, My Dear Watson" - Sherlock Holmes
This phrase may have been spoken since by Sherlock to his assistant, Doctor Watson, in any number of television and film adaptations since, but it in fact never appears even once in Arthur Conan Doyle's books.
There are a few extremely similar quotes, but Sherlock never used those four words together in that fashion. Sort of ruins the legend of Sherlock just a little bit...
