Dave Barry wrote a bizarre (even for him) column Saturday on "Talk Like A Pirate Day." It got me wondering: were there ever actual pirates who talked anything like this, used any expressions like "avast, ye mateys?" If so, how did they wind up talking like that? If not, where did the theatrical stereotype of 'pirate talk' come from? Without having read the book or studied the issue, I'm guessing Robert Louis Stevenson's "Treasure Island," but I could be wrong.
