Arr ye matey, today be th' day we celebrate International Talk Like A Buccanneer(Pirate) Day!
And, if ye dasn't know how t' talk like a swashbuckler, ye can take this site fer a test run: http://www.syddware.com/cgi-bin/pirate.pl
(yes, I typed all that myself)
I also set Google to display in Pirate (Google -> Language Tools). You can do the same with Facebook, but I don't know how exactly.
