Here is something neat to do in Facebook. Don’t worry its completely reversible in case you are jittery about your FB account.
Log-in to your account, scroll to the bottom of the page, and there it would most likely say English (US).
Click on it and change it to English (Pirates), and your Facebook will now be changed to the English that was spoken by Pirates. Its fun to watch!
Revert back once your get tired of it.
