Under the language settings of Facebook I've found a few strange oddities, apart from the usual different languages, you can change your pages to display Pirate English.

Pokes are now Stabs

Friends are now Mateys

News feed is now Fresh Booty

and many more...

To change it, go to the bottom of your Facebook homepage click on where it says "Facebook 2010 English (uk)" or whatever language you're using, and change it to English (Pirate)

So simple but yet it's just made my Friday afternoon
