People get real silly on Facebook.  Airing all their business out there, saying things they wouldn't ever say in real life (at least I hope not anyway).  But remember kids: Facebook is still public, and you still look like a fool.  

To prove this point, these guys are going to reenact a Facebook conversation for you.

Yup, straight foolish.  So remember kids, if you wouldn't say it out loud, don't say it anywhere.
