That saying just doesn't have any strong originality.
It has also been said that circa 1906, when George Bernard Shaw was invited to Henry Irving's funeral, he said "If I were at Westminister, Henry Irving would turn in his grave, just as Shakespeare would turn in his grave were Henry Irving at Stratford," implying that Irving's productions of Shakespeare would have made the actor as offensive to Shakespeare as Shaw had made himself offensive to Irving with the numerous critical reviews he had written of Irving's work. In 1902, the work Current Literature stated that "William Morris might well turn in his grave if he could see the uses to which his fine dreams of beautiful books have been put." Where the sorry state of people's spelling/punctuation/literary skills come under criticism, the act is generally said to make "Shakespeare turn in his grave," as he is associated with high literary standards. One example of this is when a national newspaper opined that writing the word "cough" with an "F" would cause such a thing to occur.
