For a start, there are far too many wrongly attributed quotes out there.
One of the popular victims is Mark Twain.
You should never trust all those books and quotation websites which published quotes wrongly credited to Mark Twain.
They just copied from one another, without bother to check their authenticity.
Never Trust A Man Who Misattributed Quotations To Mark Twain
Of course the quotation “Never trust a man who simply attributes quotations to me” is not by American author and humorist Mark Twain or his actual name Samuel Langhorne Clemens!
It is my own original quote to mock or ridicule those websites which simply published quotations without citing sources.
But sadly, the above quote attributed to Mark Twain can be found almost every where.
Remember back in 1992, the former vice-President Of America Dan Quayle used it, when he wrongly spelt the word “potato” as “potatoe”.
The press highlighted that there is no such quotation: “You should never trust a man who has only one way to spell a word” by Mark Twain.
Oh yes, this Mark Twain misquote is also found in Newsweek, Vol.127.
By the way, there is this quote about spelling by Mark Twain:
“…I never had any large respect for good spelling.” – Mark Twain
(Mark Twain’s Autobiography In 2 volumes, Vol. 2 By Albert Bigelow Paine, Harper & Brothers, 1924, Wednesday, February 7, 1906, Susy Clemens’s biography of her father.–Mr. Clemens’s opinion of critics, etc)
So, please be cautious when using quotes.
Most of these sites, they do not verified their work.
Of course, there is more than one way to find authentic Mark Twain quotations.
