Today is International Talk Like A Pirate Day. Now, you might notice that the BBC lists "Friday, September 19th" as Talk Like A Pirate day. As long as you're not a complete idiot, you also know that today is Tuesday- not Friday- and it is indeed the 19th. My sister attended a "Talk Like A Pirate Day" party last Friday. So that leads me to question what the actual date is that we are prone to talk like pirates.
At any rate, shiver me timbers, aye, and all that jazz. It's time to talk like a pirate!
