Only recommended for those familiar with Facebook or pirates- simply change the language from English (UK) to English (pirate). Example text (for finding friends):
Find yer mateys on ye olde Facebook
Yer mateys on ye olde Facebook vessel be the same crew with whom ye plunder and pillage about the seven seas. Scour this here den of villainry n' recruit yar dirty sea dogs ye may be acquainted with.
At least Facebook's now a bit more interesting.
