One of my favorite quote investigations: whether Stalin said, "A single death is a tragedy; a million deaths is a statistic."
Quotes that sound nice irrespective of the origina are probably apocryphal.
Yes, the site doesn't cover all quotes. But the large number of mis-attributed quotes I've seen shared has made me conservative in what quotes I reshare.
This is my favorite Mark Twain misquote because it's self-referential.
Or in other words: "The most famous sentence Mark Twain ever put to paper was written by anonymous."
