If you scroll down to the lower left corner of your profile you will see a current language setting. Click on that and you will be looking for a list of all languages available to you. Look for the option that says English Pirate.

Now, as you go through your profile page you should notice some pretty funny variations.

You will now notice that your wall is a plank, your profile is a captains log, and you can either click a post as pleasing to me eye (like) or blabber t’yer mates (comment). It will certainly add some character to your Facebook profile!
