George Bernard Shaw's finest work

GBS is often quoted as saying England and America are two countries divided by a common language, which is a really amusing and descriptive quote, except that he never said that. Oh well, it's a great misquote. This lovely page mentions some of the most well known misquotes. What? You mean Kirk never told Scotty to "Beam me up"?

One of the things that's interesting to me is the persistence of misinformation. I suspect the Internet has made this sort of mythology harder to eradicate. Once it appears in one place, and then gets referenced elsewhere, it's even harder to correct. Even if you remove a web page, many times a saved version of it remains in Google's cache or the Wayback machine archive.
