"I remember etaoin shrdlu, but have forgotten its origin just now."

Hi, Websafe. Those are the 12 most frequently occurring letters in English. So I've always been told, but my sister says it ain't so. She memorized the whole alphabet in order of letter frequency and "e" was still number one but the rest were different from the old "etaoin shrdlu" formula. And anyway it probably depends on what kind of English you speak.
