I've got a good one.
A person at our sister park had a facebook. She introduced her boss, to FB. However, the person forgot she had "My boss is such a bitch!" on her facebook. Idiot.
Course she won't get fired. Federal employee and all.
I've got a FB, but it's sanitized, has one photo for my profile, and is only used to communicate with my GF in the chat feature. And I only visit it on my computer.
