If you are interested in trying something new on Facebook, scroll down to the bottom of the page and click on English which is next to the Facebook copyright. Mind you, it will be difficult to scroll to the bottom of your news feed page, as you scroll down it will load up more posts and move the bottom of the page further down. Once you get to the bottom click on the language link (mine was English (US))
And then on the next screen choose English (Pirate). Now you will experience a lot of fun things with your Facebook page.
And even if you log out, you’ll get some fun Pirate awesomeness.
